"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."

"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."

"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."

"NOTE: This kernel update marks the final planned kernel security
update for the 2.6.24 kernel in the Debian release 'etch'. Although
security support for 'etch' officially ended on Feburary 15th, 2010,
this update was already in preparation before that date.

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-2009-2691
    Steve Beattie and Kees Cook reported an information leak
    in the maps and smaps files available under /proc. Local
    users may be able to read this data for setuid processes
    while the ELF binary is being loaded.

  - CVE-2009-2695
    Eric Paris provided several fixes to increase the
    protection provided by the mmap_min_addr tunable against
    NULL pointer dereference vulnerabilities.

  - CVE-2009-3080
    Dave Jones reported an issue in the gdth SCSI driver. A
    missing check for negative offsets in an ioctl call
    could be exploited by local users to create a denial of
    service or potentially gain elevated privileges.

  - CVE-2009-3726
    Trond Myklebust reported an issue where a malicious NFS
    server could cause a denial of service condition on its
    clients by returning incorrect attributes during an open
    call.

  - CVE-2009-3889
    Joe Malicki discovered an issue in the megaraid_sas
    driver. Insufficient permissions on the sysfs dbg_lvl
    interface allow local users to modify the debug logging
    behavior.

  - CVE-2009-4005
    Roel Kluin discovered an issue in the hfc_usb driver, an
    ISDN driver for Colognechip HFC-S USB chip. A potential
    read overflow exists which may allow remote users to
    cause a denial of service condition (oops).

  - CVE-2009-4020
    Amerigo Wang discovered an issue in the HFS filesystem
    that would allow a denial of service by a local user who
    has sufficient privileges to mount a specially crafted
    filesystem.

  - CVE-2009-4021
    Anana V. Avati discovered an issue in the fuse
    subsystem. If the system is sufficiently low on memory,
    a local user can cause the kernel to dereference an
    invalid pointer resulting in a denial of service (oops)
    and potentially an escalation of privileges.

  - CVE-2009-4138
    Jay Fenlason discovered an issue in the firewire stack
    that allows local users to cause a denial of service
    (oops or crash) by making a specially crafted ioctl
    call.

  - CVE-2009-4308
    Ted Ts'o discovered an issue in the ext4 filesystem that
    allows local users to cause a denial of service (NULL
    pointer dereference). For this to be exploitable, the
    local user must have sufficient privileges to mount a
    filesystem.

  - CVE-2009-4536 CVE-2009-4538
    Fabian Yamaguchi reported issues in the e1000 and e1000e
    drivers for Intel gigabit network adapters which allow
    remote users to bypass packet filters using specially
    crafted Ethernet frames.

  - CVE-2010-0003
    Andi Kleen reported a defect which allows local users to
    gain read access to memory reachable by the kernel when
    the print-fatal-signals option is enabled. This option
    is disabled by default.

  - CVE-2010-0007
    Florian Westphal reported a lack of capability checking
    in the ebtables netfilter subsystem. If the ebtables
    module is loaded, local users can add and modify
    ebtables rules.

  - CVE-2010-0291
    Al Viro reported several issues with the mmap/mremap
    system calls that allow local users to cause a denial of
    service (system panic) or obtain elevated privileges.

  - CVE-2010-0410
    Sebastian Krahmer discovered an issue in the netlink
    connector subsystem that permits local users to allocate
    large amounts of system memory resulting in a denial of
    service (out of memory).

  - CVE-2010-0415
    Ramon de Carvalho Valle discovered an issue in the
    sys_move_pages interface, limited to amd64, ia64 and
    powerpc64 flavors in Debian. Local users can exploit
    this issue to cause a denial of service (system crash)
    or gain access to sensitive kernel memory.

  - CVE-2010-0622
    Jerome Marchand reported an issue in the futex subsystem
    that allows a local user to force an invalid futex state
    which results in a denial of service (oops)."

"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."
