"Updated kernel packages that fix security issues are now available for
Red Hat Enterprise Linux 4.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

This update fixes the following security issues :

* a NULL pointer dereference flaw was found in each of the following
functions in the Linux kernel: pipe_read_open(), pipe_write_open(),
and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe
pointer could be released by other processes before it is used to
update the pipe's reader and writer counters. This could lead to a
local denial of service or privilege escalation. (CVE-2009-3547,
Important)

Users should upgrade to these updated packages, which contain a
backported patch to correct these issues. The system must be rebooted
for this update to take effect."

"a. vMA and Service Console update for newt to 0.52.2-12.el5_4.1

   Newt is a programming library for color text mode, widget based
   user interfaces. Newt can be used to add stacked windows, entry
   widgets, checkboxes, radio buttons, labels, plain text fields,
   scrollbars, etc., to text mode user interfaces.

   A heap-based buffer overflow flaw was found in the way newt
   processes content that is to be displayed in a text dialog box.
   A local attacker could issue a specially crafted text dialog box
   display request (direct or via a custom application), leading to a
   denial of service (application crash) or, potentially, arbitrary
   code execution with the privileges of the user running the
   application using the newt library.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)
   has assigned the name CVE-2009-2905 to this issue.

b. vMA and Service Console update for vMA package nfs-utils to
   1.0.9-42.el5

   The nfs-utils package provides a daemon for the kernel NFS server
   and related tools.

   It was discovered that nfs-utils did not use tcp_wrappers
   correctly.  Certain hosts access rules defined in '/etc/hosts.allow'
   and '/etc/hosts.deny' may not have been honored, possibly allowing
   remote attackers to bypass intended access restrictions.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)
   has assigned the name CVE-2008-4552 to this issue.

c. vMA and Service Console package glib2 updated to 2.12.3-4.el5_3.1

   GLib is the low-level core library that forms the basis for
   projects such as GTK+ and GNOME. It provides data structure
   handling for C, portability wrappers, and interfaces for such
   runtime functionality as an event loop, threads, dynamic loading,
   and an object system.

   Multiple integer overflows in glib/gbase64.c in GLib before 2.20
   allow context-dependent attackers to execute arbitrary code via a
   long string that is converted either from or to a base64
   representation.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)
   has assigned the name CVE-2008-4316 to this issue.

d. vMA and Service Console update for openssl to 0.9.8e-12.el5

   SSL is a toolkit implementing SSL v2/v3 and TLS protocols with full-
   strength cryptography world-wide.

   Multiple denial of service flaws were discovered in OpenSSL's DTLS
   implementation. A remote attacker could use these flaws to cause a
   DTLS server to use excessive amounts of memory, or crash on an
   invalid memory access or NULL pointer dereference.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)
   has assigned the names CVE-2009-1377, CVE-2009-1378,
   CVE-2009-1379, CVE-2009-1386, CVE-2009-1387 to these issues.

   An input validation flaw was found in the handling of the BMPString
   and UniversalString ASN1 string types in OpenSSL's
   ASN1_STRING_print_ex() function. An attacker could use this flaw to
   create a specially crafted X.509 certificate that could cause
   applications using the affected function to crash when printing
   certificate contents.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)
   has assigned the name CVE-2009-0590 to this issue.

e. vMA and Service Console package bind updated to 9.3.6-4.P1.el5_4.1

   It was discovered that BIND was incorrectly caching responses
   without performing proper DNSSEC validation, when those responses
   were received during the resolution of a recursive client query
   that requested DNSSEC records but indicated that checking should be
   disabled. A remote attacker could use this flaw to bypass the DNSSEC
   validation check and perform a cache poisoning attack if the target
   BIND server was receiving such client queries.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)
   has assigned the name CVE-2009-4022 to this issue.

f. vMA and Service Console package expat updated to 1.95.8-8.3.el5_4.2.

   Two buffer over-read flaws were found in the way Expat handled
   malformed UTF-8 sequences when processing XML files. A specially-
   crafted XML file could cause applications using Expat to fail while
   parsing the file.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)
   has assigned the names CVE-2009-3560 and CVE-2009-3720 to these
   issues.

g. vMA and Service Console package openssh update to 4.3p2-36.el5_4.2

   A Red Hat specific patch used in the openssh packages as shipped in
   Red Hat Enterprise Linux 5.4 (RHSA-2009:1287) loosened certain
   ownership requirements for directories used as arguments for the
   ChrootDirectory configuration options. A malicious user that also
   has or previously had non-chroot shell access to a system could
   possibly use this flaw to escalate their privileges and run
   commands as any system user.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)
   has assigned the name CVE-2009-2904 to this issue.

h. vMA and Service Console package ntp updated to
   ntp-4.2.2p1-9.el5_4.1.i386.rpm

   A flaw was discovered in the way ntpd handled certain malformed NTP
   packets. ntpd logged information about all such packets and replied
   with an NTP packet that was treated as malformed when received by
   another ntpd. A remote attacker could use this flaw to create an NTP
   packet reply loop between two ntpd servers through a malformed packet
   with a spoofed source IP address and port, causing ntpd on those
   servers to use excessive amounts of CPU time and fill disk space with
   log messages.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)
   has assigned the name CVE-2009-3563 to this issue.   

i. vMA update for package kernel to 2.6.18-164.9.1.el5

   Updated vMA package kernel addresses the security issues listed
   below.

   The Common Vulnerabilities and Exposures project (cve.mitre.org)
   has assigned the name CVE-2009-2849 to the security issue fixed in
   kernel 2.6.18-128.2.1

   The Common Vulnerabilities and Exposures project (cve.mitre.org)
   has assigned the names CVE-2009-2695, CVE-2009-2908, CVE-2009-3228,
   CVE-2009-3286, CVE-2009-3547, CVE-2009-3613 to the security issues
   fixed in kernel 2.6.18-128.6.1

   The Common Vulnerabilities and Exposures project (cve.mitre.org)
   has assigned the names CVE-2009-3612, CVE-2009-3620, CVE-2009-3621,
   CVE-2009-3726 to the security issues fixed in kernel
   2.6.18-128.9.1

j. vMA 4.0 updates for the packages kpartx, libvolume-id,
   device-mapper-multipath, fipscheck, dbus, dbus-libs, and ed

   kpartx updated to 0.4.7-23.el5_3.4, libvolume-id updated to
   095-14.20.el5 device-mapper-multipath package updated to
   0.4.7-23.el5_3.4, fipscheck updated to 1.0.3-1.el5, dbus
   updated to 1.1.2-12.el5, dbus-libs updated to 1.1.2-12.el5,

This update has been rated as having important security impact by the
Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

This update fixes the following security issues :

* a NULL pointer dereference flaw was found in each of the following
functions in the Linux kernel: pipe_read_open(), pipe_write_open(),
and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe
pointer could be released by other processes before it is used to
update the pipe's reader and writer counters. This could lead to a
local denial of service or privilege escalation. (CVE-2009-3547,
Important)

Users should upgrade to these updated packages, which contain a
backported patch to correct these issues. The system must be rebooted
for this update to take effect."

"Updated kernel packages that fix several security issues and multiple
bugs are now available for Red Hat Enterprise Linux 3.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security fixes :

* when fput() was called to close a socket, the __scm_destroy()
function in the Linux kernel could make indirect recursive calls to
itself. This could, potentially, lead to a denial of service issue.
(CVE-2008-5029, Important)

* the sendmsg() function in the Linux kernel did not block during UNIX
socket garbage collection. This could, potentially, lead to a local
denial of service. (CVE-2008-5300, Important)

* the exit_notify() function in the Linux kernel did not properly
reset the exit signal if a process executed a set user ID (setuid)
application before exiting. This could allow a local, unprivileged
user to elevate their privileges. (CVE-2009-1337, Important)

* a flaw was found in the Intel PRO/1000 network driver in the Linux
kernel. Frames with sizes near the MTU of an interface may be split
across multiple hardware receive descriptors. Receipt of such a frame
could leak through a validation check, leading to a corruption of the
length check. A remote attacker could use this flaw to send a
specially crafted packet that would cause a denial of service or code
execution. (CVE-2009-1385, Important)

* the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared
when a setuid or setgid program was executed. A local, unprivileged
user could use this flaw to bypass the mmap_min_addr protection
mechanism and perform a NULL pointer dereference attack, or bypass the
Address Space Layout Randomization (ASLR) security feature.
(CVE-2009-1895, Important)

* it was discovered that, when executing a new process, the
clear_child_tid pointer in the Linux kernel is not cleared. If this
pointer points to a writable portion of the memory of the new program,
the kernel could corrupt four bytes of memory, possibly leading to a
local denial of service or privilege escalation. (CVE-2009-2848,
Important)

* missing initialization flaws were found in getname() implementations
in the IrDA sockets, AppleTalk DDP protocol, NET/ROM protocol, and
ROSE protocol implementations in the Linux kernel. Certain data
structures in these getname() implementations were not initialized
properly before being copied to user-space. These flaws could lead to
an information leak. (CVE-2009-3002, Important)

* a NULL pointer dereference flaw was found in each of the following
functions in the Linux kernel: pipe_read_open(), pipe_write_open(),
and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe
pointer could be released by other processes before it is used to
update the pipe's reader and writer counters. This could lead to a
local denial of service or privilege escalation. (CVE-2009-3547,
Important)

Bug fixes :

* this update adds the mmap_min_addr tunable and restriction checks to
help prevent unprivileged users from creating new memory mappings
below the minimum address. This can help prevent the exploitation of
NULL pointer dereference bugs. Note that mmap_min_addr is set to zero
(disabled) by default for backwards compatibility. (BZ#512642)

* a bridge reference count problem in IPv6 has been fixed. (BZ#457010)

* enforce null-termination of user-supplied arguments to setsockopt().
(BZ#505514)

* the gcc flag '-fno-delete-null-pointer-checks' was added to the
kernel build options. This prevents gcc from optimizing out NULL
pointer checks after the first use of a pointer. NULL pointer bugs are
often exploited by attackers. Keeping these checks is a safety
measure. (BZ#511185)

* a check has been added to the IPv4 code to make sure that rt is not
NULL, to help prevent future bugs in functions that call
ip_append_data() from being exploitable. (BZ#520300)

Users should upgrade to these updated packages, which contain
backported patches to correct these issues. The system must be
rebooted for this update to take effect."

"Several vulnerabilities have been discovered in the Linux kernel that
may lead to a denial of service, sensitive memory leak or privilege
escalation. The Common Vulnerabilities and Exposures project
identifies the following problems :

  - CVE-2009-2846
    Michael Buesch noticed a typing issue in the eisa-eeprom
    driver for the hppa architecture. Local users could
    exploit this issue to gain access to restricted memory.

  - CVE-2009-2847
    Ulrich Drepper noticed an issue in the do_sigalstack
    routine on 64-bit systems. This issue allows local users
    to gain access to potentially sensitive memory on the
    kernel stack.

  - CVE-2009-2848
    Eric Dumazet discovered an issue in the execve path,
    where the clear_child_tid variable was not being
    properly cleared. Local users could exploit this issue
    to cause a denial of service (memory corruption).

  - CVE-2009-2849
    Neil Brown discovered an issue in the sysfs interface to
    md devices. When md arrays are not active, local users
    can exploit this vulnerability to cause a denial of
    service (oops).

  - CVE-2009-2903
    Mark Smith discovered a memory leak in the appletalk
    implementation. When the appletalk and ipddp modules are
    loaded, but no ipddp'N' device is found, remote
    attackers can cause a denial of service by consuming
    large amounts of system memory.

  - CVE-2009-2908
    Loic Minier discovered an issue in the eCryptfs
    filesystem. A local user can cause a denial of service
    (kernel oops) by causing a dentry value to go negative.

  - CVE-2009-2909
    Arjan van de Ven discovered an issue in the AX.25
    protocol implementation. A specially crafted call to
    setsockopt() can result in a denial of service (kernel
    oops).

  - CVE-2009-2910
    Jan Beulich discovered the existence of a sensitive
    kernel memory leak. Systems running the 'amd64' kernel
    do not properly sanitize registers for 32-bit processes.

  - CVE-2009-3001
    Jiri Slaby fixed a sensitive memory leak issue in the
    ANSI/IEEE 802.2 LLC implementation. This is not
    exploitable in the Debian lenny kernel as root
    privileges are required to exploit this issue.

  - CVE-2009-3002
    Eric Dumazet fixed several sensitive memory leaks in the
    IrDA, X.25 PLP (Rose), NET/ROM, Acorn Econet/AUN, and
    Controller Area Network (CAN) implementations. Local
    users can exploit these issues to gain access to kernel
    memory.

  - CVE-2009-3228
    Eric Dumazet reported an instance of uninitialized
    kernel memory in the network packet scheduler. Local
    users may be able to exploit this issue to read the
    contents of sensitive kernel memory.

  - CVE-2009-3238
    Linus Torvalds provided a change to the get_random_int()
    function to increase its randomness.

  - CVE-2009-3286
    Eric Paris discovered an issue with the NFSv4 server
    implementation. When an O_EXCL create fails, files may
    be left with corrupted permissions, possibly granting
    unintentional privileges to other local users.

  - CVE-2009-3547
    Earl Chew discovered a NULL pointer dereference issue in
    the pipe_rdwr_open function which can be used by local
    users to gain elevated privileges.

  - CVE-2009-3612
    Jiri Pirko discovered a typo in the initialization of a
    structure in the netlink subsystem that may allow local
    users to gain access to sensitive kernel memory.

  - CVE-2009-3613
    Alistair Strachan reported an issue in the r8169 driver.
    Remote users can cause a denial of service (IOMMU space
    exhaustion and system crash) by transmitting a large
    amount of jumbo frames.

  - CVE-2009-3620
    Ben Hutchings discovered an issue in the DRM manager for
    ATI Rage 128 graphics adapters. Local users may be able
    to exploit this vulnerability to cause a denial of
    service (NULL pointer dereference).

  - CVE-2009-3621
    Tomoki Sekiyama discovered a deadlock condition in the
    UNIX domain socket implementation. Local users can
    exploit this vulnerability to cause a denial of service
    (system hang)."

For the oldstable distribution (etch), this problem has been fixed in

Note: Debian 'etch' includes linux kernel packages based upon both the
2.6.18 and 2.6.24 linux releases. All known security issues are
carefully tracked against both packages and both packages will receive
security updates until security support for Debian 'etch' concludes.
However, given the high frequency at which low-severity security

doing an update, lower severity 2.6.18 and 2.6.24 updates will
typically release in a staggered or 'leap-frog' fashion."

"From Red Hat Security Advisory 2009:1550 :

Updated kernel packages that fix several security issues and multiple
bugs are now available for Red Hat Enterprise Linux 3.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security fixes :

* when fput() was called to close a socket, the __scm_destroy()
function in the Linux kernel could make indirect recursive calls to
itself. This could, potentially, lead to a denial of service issue.
(CVE-2008-5029, Important)

* the sendmsg() function in the Linux kernel did not block during UNIX
socket garbage collection. This could, potentially, lead to a local
denial of service. (CVE-2008-5300, Important)

* the exit_notify() function in the Linux kernel did not properly
reset the exit signal if a process executed a set user ID (setuid)
application before exiting. This could allow a local, unprivileged
user to elevate their privileges. (CVE-2009-1337, Important)

* a flaw was found in the Intel PRO/1000 network driver in the Linux
kernel. Frames with sizes near the MTU of an interface may be split
across multiple hardware receive descriptors. Receipt of such a frame
could leak through a validation check, leading to a corruption of the
length check. A remote attacker could use this flaw to send a
specially crafted packet that would cause a denial of service or code
execution. (CVE-2009-1385, Important)

* the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared
when a setuid or setgid program was executed. A local, unprivileged
user could use this flaw to bypass the mmap_min_addr protection
mechanism and perform a NULL pointer dereference attack, or bypass the
Address Space Layout Randomization (ASLR) security feature.
(CVE-2009-1895, Important)

* it was discovered that, when executing a new process, the
clear_child_tid pointer in the Linux kernel is not cleared. If this
pointer points to a writable portion of the memory of the new program,
the kernel could corrupt four bytes of memory, possibly leading to a
local denial of service or privilege escalation. (CVE-2009-2848,
Important)

* missing initialization flaws were found in getname() implementations
in the IrDA sockets, AppleTalk DDP protocol, NET/ROM protocol, and
ROSE protocol implementations in the Linux kernel. Certain data
structures in these getname() implementations were not initialized
properly before being copied to user-space. These flaws could lead to
an information leak. (CVE-2009-3002, Important)

* a NULL pointer dereference flaw was found in each of the following
functions in the Linux kernel: pipe_read_open(), pipe_write_open(),
and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe
pointer could be released by other processes before it is used to
update the pipe's reader and writer counters. This could lead to a
local denial of service or privilege escalation. (CVE-2009-3547,
Important)

Bug fixes :

* this update adds the mmap_min_addr tunable and restriction checks to
help prevent unprivileged users from creating new memory mappings
below the minimum address. This can help prevent the exploitation of
NULL pointer dereference bugs. Note that mmap_min_addr is set to zero
(disabled) by default for backwards compatibility. (BZ#512642)

* a bridge reference count problem in IPv6 has been fixed. (BZ#457010)

* enforce null-termination of user-supplied arguments to setsockopt().
(BZ#505514)

* the gcc flag '-fno-delete-null-pointer-checks' was added to the
kernel build options. This prevents gcc from optimizing out NULL
pointer checks after the first use of a pointer. NULL pointer bugs are
often exploited by attackers. Keeping these checks is a safety
measure. (BZ#511185)

* a check has been added to the IPv4 code to make sure that rt is not
NULL, to help prevent future bugs in functions that call
ip_append_data() from being exploitable. (BZ#520300)

Users should upgrade to these updated packages, which contain
backported patches to correct these issues. The system must be
rebooted for this update to take effect."

"From Red Hat Security Advisory 2009:1455 :

Updated kernel packages that fix one security issue and several bugs
are now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

[Updated 23rd February 2010] This update adds references to two KBase
articles that includes greater detail regarding some bug fixes that
could not be fully documented in the errata note properly.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security fix :

* a NULL pointer dereference flaw was found in the Multiple Devices
(md) driver in the Linux kernel. If the 'suspend_lo' or 'suspend_hi'
file on the sysfs file system ('/sys/') is modified when the disk
array is inactive, it could lead to a local denial of service or
privilege escalation. Note: By default, only the root user can write
to the files noted above. (CVE-2009-2849, Moderate)

Bug fixes :

* a bug in nlm_lookup_host() could lead to un-reclaimed file system
locks, resulting in umount failing & NFS service relocation issues for
clusters. (BZ#517967)

* a bug in the sky2 driver prevented the phy from being reset properly
on some hardware when it hung, preventing a link from coming back up.
(BZ#517976)

* disabling MSI-X for qla2xxx also disabled MSI interrupts.
(BZ#519782)

* performance issues with reads when using the qlge driver on PowerPC
systems. A system hang could also occur during reboot. (BZ#519783)

* unreliable time keeping for Red Hat Enterprise Linux virtual
machines. The KVM pvclock code is now used to detect/correct lost
ticks. (BZ#520685)

* /proc/cpuinfo was missing flags for new features in supported
processors, possibly preventing the operating system & applications
from getting the best performance. (BZ#520686)

* reading/writing with a serial loopback device on a certain IBM
system did not work unless booted with 'pnpacpi=off'. (BZ#520905)

* mlx4_core failed to load on systems with more than 32 CPUs.
(BZ#520906)

* on big-endian platforms, interfaces using the mlx4_en driver & Large
Receive Offload (LRO) did not handle VLAN traffic properly (a
segmentation fault in the VLAN stack in the kernel occurred).
(BZ#520908)

* due to a lock being held for a long time, some systems may have
experienced 'BUG: soft lockup' messages under heavy load. (BZ#520919)

* incorrect APIC timer calibration may have caused a system hang
during boot, as well as the system time becoming faster or slower. A
warning is now provided. (BZ#521238)

* a Fibre Channel device re-scan via 'echo '---' >
/sys/class/scsi_host/ host[x]/scan' may not complete after hot adding
a drive, leading to soft lockups ('BUG: soft lockup detected').
(BZ#521239)

* the Broadcom BCM5761 network device could not to be initialized
properly; therefore, the associated interface could not obtain an IP
address via DHCP or be assigned one manually. (BZ#521241)

* when a process attempted to read from a page that had first been
accessed by writing to part of it (via write(2)), the NFS client
needed to flush the modified portion of the page out to the server, &
then read the entire page back in. This flush caused performance
issues. (BZ#521244)

* a kernel panic when using bnx2x devices & LRO in a bridge. A warning
is now provided to disable LRO in these situations. (BZ#522636)

* the scsi_dh_rdac driver was updated to recognize the Sun StorageTek
Flexline 380. (BZ#523237)

* in FIPS mode, random number generators are required to not return
the first block of random data they generate, but rather save it to
seed the repetition check. This update brings the random number
generator into conformance. (BZ#523289)

* an option to disable/enable the use of the first random block is now
provided to bring ansi_cprng into compliance with FIPS-140 continuous
test requirements. (BZ#523290)

* running the SAP Linux Certification Suite in a KVM guest caused
severe SAP kernel errors, causing it to exit. (BZ#524150)

* attempting to 'online' a CPU for a KVM guest via sysfs caused a
system crash. (BZ#524151)

* when using KVM, pvclock returned bogus wallclock values. (BZ#524152)

* the clock could go backwards when using the vsyscall infrastructure.
(BZ#524527)

See References for KBase links re BZ#519782 & BZ#520906.

Users should upgrade to these updated packages, which contain
backported patches to correct these issues. Reboot the system for this

"Updated kernel packages that fix multiple security issues and several
bugs are now available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security fixes :

* a system with SELinux enforced was more permissive in allowing local
users in the unconfined_t domain to map low memory areas even if the
mmap_min_addr restriction was enabled. This could aid in the local
exploitation of NULL pointer dereference bugs. (CVE-2009-2695,
Important)

* a NULL pointer dereference flaw was found in the eCryptfs
implementation in the Linux kernel. A local attacker could use this
flaw to cause a local denial of service or escalate their privileges.
(CVE-2009-2908, Important)

* a flaw was found in the NFSv4 implementation. The kernel would do an
unnecessary permission check after creating a file. This check would
usually fail and leave the file with the permission bits set to random
values. Note: This is a server-side only issue. (CVE-2009-3286,
Important)

* a NULL pointer dereference flaw was found in each of the following
functions in the Linux kernel: pipe_read_open(), pipe_write_open(),
and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe
pointer could be released by other processes before it is used to
update the pipe's reader and writer counters. This could lead to a
local denial of service or privilege escalation. (CVE-2009-3547,
Important)

* a flaw was found in the Realtek r8169 Ethernet driver in the Linux
kernel. pci_unmap_single() presented a memory leak that could lead to
IOMMU space exhaustion and a system crash. An attacker on the local
network could abuse this flaw by using jumbo frames for large amounts
of network traffic. (CVE-2009-3613, Important)

* missing initialization flaws were found in the Linux kernel. Padding
data in several core network structures was not initialized properly
before being sent to user-space. These flaws could lead to information
leaks. (CVE-2009-3228, Moderate)

Bug fixes :

* with network bonding in the 'balance-tlb' or 'balance-alb' mode, the
primary setting for the primary slave device was lost when said device
was brought down. Bringing the slave back up did not restore the
primary setting. (BZ#517971)

* some faulty serial device hardware caused systems running the
kernel-xen kernel to take a very long time to boot. (BZ#524153)

* a caching bug in nfs_readdir() may have caused NFS clients to see
duplicate files or not see all files in a directory. (BZ#526960)

* the RHSA-2009:1243 update removed the mpt_msi_enable option,
preventing certain scripts from running. This update adds the option
back. (BZ#526963)

* an iptables rule with the recent module and a hit count value
greater than the ip_pkt_list_tot parameter (the default is 20), did
not have any effect over packets, as the hit count could not be
reached. (BZ#527434)

* a check has been added to the IPv4 code to make sure that rt is not
NULL, to help prevent future bugs in functions that call
ip_append_data() from being exploitable. (BZ#527436)

* a kernel panic occurred in certain conditions after reconfiguring a
tape drive's block size. (BZ#528133)

* when using the Linux Virtual Server (LVS) in a master and backup
configuration, and propagating active connections on the master to the
backup, the connection timeout value on the backup was hard-coded to
180 seconds, meaning connection information on the backup was soon
lost. This could prevent the successful failover of connections. The
timeout value can now be set via 'ipvsadm --set'. (BZ#528645)

* a bug in nfs4_do_open_expired() could have caused the reclaimer
thread on an NFSv4 client to enter an infinite loop. (BZ#529162)

* MSI interrupts may not have been delivered for r8169 based network
cards that have MSI interrupts enabled. This bug only affected certain
systems. (BZ#529366)

Users should upgrade to these updated packages, which contain
backported patches to correct these issues. The system must be
rebooted for this update to take effect."

"Updated kernel packages that fix one security issue and several bugs
are now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

[Updated 23rd February 2010] This update adds references to two KBase
articles that includes greater detail regarding some bug fixes that
could not be fully documented in the errata note properly.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security fix :

* a NULL pointer dereference flaw was found in the Multiple Devices
(md) driver in the Linux kernel. If the 'suspend_lo' or 'suspend_hi'
file on the sysfs file system ('/sys/') is modified when the disk
array is inactive, it could lead to a local denial of service or
privilege escalation. Note: By default, only the root user can write
to the files noted above. (CVE-2009-2849, Moderate)

Bug fixes :

* a bug in nlm_lookup_host() could lead to un-reclaimed file system
locks, resulting in umount failing & NFS service relocation issues for
clusters. (BZ#517967)

* a bug in the sky2 driver prevented the phy from being reset properly
on some hardware when it hung, preventing a link from coming back up.
(BZ#517976)

* disabling MSI-X for qla2xxx also disabled MSI interrupts.
(BZ#519782)

* performance issues with reads when using the qlge driver on PowerPC
systems. A system hang could also occur during reboot. (BZ#519783)

* unreliable time keeping for Red Hat Enterprise Linux virtual
machines. The KVM pvclock code is now used to detect/correct lost
ticks. (BZ#520685)

* /proc/cpuinfo was missing flags for new features in supported
processors, possibly preventing the operating system & applications
from getting the best performance. (BZ#520686)

* reading/writing with a serial loopback device on a certain IBM
system did not work unless booted with 'pnpacpi=off'. (BZ#520905)

* mlx4_core failed to load on systems with more than 32 CPUs.
(BZ#520906)

* on big-endian platforms, interfaces using the mlx4_en driver & Large
Receive Offload (LRO) did not handle VLAN traffic properly (a
segmentation fault in the VLAN stack in the kernel occurred).
(BZ#520908)

* due to a lock being held for a long time, some systems may have
experienced 'BUG: soft lockup' messages under heavy load. (BZ#520919)

* incorrect APIC timer calibration may have caused a system hang
during boot, as well as the system time becoming faster or slower. A
warning is now provided. (BZ#521238)

* a Fibre Channel device re-scan via 'echo '---' >
/sys/class/scsi_host/ host[x]/scan' may not complete after hot adding
a drive, leading to soft lockups ('BUG: soft lockup detected').
(BZ#521239)

* the Broadcom BCM5761 network device could not to be initialized
properly; therefore, the associated interface could not obtain an IP
address via DHCP or be assigned one manually. (BZ#521241)

* when a process attempted to read from a page that had first been
accessed by writing to part of it (via write(2)), the NFS client
needed to flush the modified portion of the page out to the server, &
then read the entire page back in. This flush caused performance
issues. (BZ#521244)

* a kernel panic when using bnx2x devices & LRO in a bridge. A warning
is now provided to disable LRO in these situations. (BZ#522636)

* the scsi_dh_rdac driver was updated to recognize the Sun StorageTek
Flexline 380. (BZ#523237)

* in FIPS mode, random number generators are required to not return
the first block of random data they generate, but rather save it to
seed the repetition check. This update brings the random number
generator into conformance. (BZ#523289)

* an option to disable/enable the use of the first random block is now
provided to bring ansi_cprng into compliance with FIPS-140 continuous
test requirements. (BZ#523290)

* running the SAP Linux Certification Suite in a KVM guest caused
severe SAP kernel errors, causing it to exit. (BZ#524150)

* attempting to 'online' a CPU for a KVM guest via sysfs caused a
system crash. (BZ#524151)

* when using KVM, pvclock returned bogus wallclock values. (BZ#524152)

* the clock could go backwards when using the vsyscall infrastructure.
(BZ#524527)

See References for KBase links re BZ#519782 & BZ#520906.

Users should upgrade to these updated packages, which contain
backported patches to correct these issues. Reboot the system for this
update to take effect."

"Updated kernel packages that fix several security issues and multiple
bugs are now available for Red Hat Enterprise Linux 3.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security fixes :

* when fput() was called to close a socket, the __scm_destroy()
function in the Linux kernel could make indirect recursive calls to
itself. This could, potentially, lead to a denial of service issue.
(CVE-2008-5029, Important)

* the sendmsg() function in the Linux kernel did not block during UNIX
socket garbage collection. This could, potentially, lead to a local
denial of service. (CVE-2008-5300, Important)

* the exit_notify() function in the Linux kernel did not properly
reset the exit signal if a process executed a set user ID (setuid)
application before exiting. This could allow a local, unprivileged
user to elevate their privileges. (CVE-2009-1337, Important)

* a flaw was found in the Intel PRO/1000 network driver in the Linux
kernel. Frames with sizes near the MTU of an interface may be split
across multiple hardware receive descriptors. Receipt of such a frame
could leak through a validation check, leading to a corruption of the
length check. A remote attacker could use this flaw to send a
specially crafted packet that would cause a denial of service or code
execution. (CVE-2009-1385, Important)

* the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared
when a setuid or setgid program was executed. A local, unprivileged
user could use this flaw to bypass the mmap_min_addr protection
mechanism and perform a NULL pointer dereference attack, or bypass the
Address Space Layout Randomization (ASLR) security feature.
(CVE-2009-1895, Important)

* it was discovered that, when executing a new process, the
clear_child_tid pointer in the Linux kernel is not cleared. If this
pointer points to a writable portion of the memory of the new program,
the kernel could corrupt four bytes of memory, possibly leading to a
local denial of service or privilege escalation. (CVE-2009-2848,
Important)

* missing initialization flaws were found in getname() implementations
in the IrDA sockets, AppleTalk DDP protocol, NET/ROM protocol, and
ROSE protocol implementations in the Linux kernel. Certain data
structures in these getname() implementations were not initialized
properly before being copied to user-space. These flaws could lead to
an information leak. (CVE-2009-3002, Important)

* a NULL pointer dereference flaw was found in each of the following
functions in the Linux kernel: pipe_read_open(), pipe_write_open(),
and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe
pointer could be released by other processes before it is used to
update the pipe's reader and writer counters. This could lead to a
local denial of service or privilege escalation. (CVE-2009-3547,
Important)

Bug fixes :

* this update adds the mmap_min_addr tunable and restriction checks to
help prevent unprivileged users from creating new memory mappings
below the minimum address. This can help prevent the exploitation of
NULL pointer dereference bugs. Note that mmap_min_addr is set to zero
(disabled) by default for backwards compatibility. (BZ#512642)

* a bridge reference count problem in IPv6 has been fixed. (BZ#457010)

* enforce null-termination of user-supplied arguments to setsockopt().
(BZ#505514)

* the gcc flag '-fno-delete-null-pointer-checks' was added to the
kernel build options. This prevents gcc from optimizing out NULL
pointer checks after the first use of a pointer. NULL pointer bugs are
often exploited by attackers. Keeping these checks is a safety
measure. (BZ#511185)

* a check has been added to the IPv4 code to make sure that rt is not
NULL, to help prevent future bugs in functions that call
ip_append_data() from being exploitable. (BZ#520300)

Users should upgrade to these updated packages, which contain
backported patches to correct these issues. The system must be
rebooted for this update to take effect."

"From Red Hat Security Advisory 2009:1541 :

Updated kernel packages that fix security issues are now available for
Red Hat Enterprise Linux 4.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

This update fixes the following security issues :

* a NULL pointer dereference flaw was found in each of the following
functions in the Linux kernel: pipe_read_open(), pipe_write_open(),
and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe
pointer could be released by other processes before it is used to
update the pipe's reader and writer counters. This could lead to a
local denial of service or privilege escalation. (CVE-2009-3547,
Important)

Users should upgrade to these updated packages, which contain a
backported patch to correct these issues. The system must be rebooted
for this update to take effect."
