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

The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

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 the sctp_rcv_ootb()
function in the Linux kernel Stream Control Transmission Protocol
(SCTP) implementation. A remote attacker could send a specially
crafted SCTP packet to a target system, resulting in a denial of
service. (CVE-2010-0008, Important)

* a NULL pointer dereference flaw was found in the Linux kernel.
During a core dump, the kernel did not check if the Virtual
Dynamically-linked Shared Object page was accessible. On Intel 64 and
AMD64 systems, a local, unprivileged user could use this flaw to cause
a kernel panic by running a crafted 32-bit application.
(CVE-2009-4271, Important)

* an information leak was found in the print_fatal_signal()
implementation in the Linux kernel. When
'/proc/sys/kernel/print-fatal-signals' is set to 1 (the default value
is 0), memory that is reachable by the kernel could be leaked to
user-space. This issue could also result in a system crash. Note that
this flaw only affected the i386 architecture. (CVE-2010-0003,
Moderate)

* on AMD64 systems, it was discovered that the kernel did not ensure
the ELF interpreter was available before making a call to the
SET_PERSONALITY macro. A local attacker could use this flaw to cause a
denial of service by running a 32-bit application that attempts to
execute a 64-bit application. (CVE-2010-0307, Moderate)

* missing capability checks were found in the ebtables implementation,
used for creating an Ethernet bridge firewall. This could allow a
local, unprivileged user to bypass intended capability restrictions
and modify ebtables rules. (CVE-2010-0007, Low)

This update also fixes the following bugs :

* under some circumstances, a locking bug could have caused an online
ext3 file system resize to deadlock, which may have, in turn, caused
the file system or the entire system to become unresponsive. In either
case, a reboot was required after the deadlock. With this update,
using resize2fs to perform an online resize of an ext3 file system
works as expected. (BZ#553135)

* some ATA and SCSI devices were not honoring the barrier=1 mount
option, which could result in data loss after a crash or power loss.
This update applies a patch to the Linux SCSI driver to ensure ordered
write caching. This solution does not provide cache flushes; however,
it does provide data integrity on devices that have no write caching
(or where write caching is disabled) and no command queuing. For
systems that have command queuing or write cache enabled there is no
guarantee of data integrity after a crash. (BZ#560563)

* it was found that lpfc_find_target() could loop continuously when
scanning a list of nodes due to a missing spinlock. This missing
spinlock allowed the list to be changed after the list_empty() test,
resulting in a NULL value, causing the loop. This update adds the
spinlock, resolving the issue. (BZ#561453)

* the fix for CVE-2009-4538 provided by RHSA-2010:0020 introduced a
regression, preventing Wake on LAN (WoL) working for network devices
using the Intel PRO/1000 Linux driver, e1000e. Attempting to configure
WoL for such devices resulted in the following error, even when
configuring valid options :

'Cannot set new wake-on-lan settings: Operation not supported not
setting wol'

This update resolves this regression, and WoL now works as expected
for network devices using the e1000e driver. (BZ#565496)

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."

"USN-947-1 fixed vulnerabilities in the Linux kernel. Fixes for
CVE-2010-0419 caused failures when using KVM in certain situations.
This update reverts that fix until a better solution can be found.

We apologize for the inconvenience.

It was discovered that the Linux kernel did not correctly handle
memory protection of the Virtual Dynamic Shared Object page when
running a 32-bit application on a 64-bit kernel. A local attacker
could exploit this to cause a denial of service. (Only affected Ubuntu
6.06 LTS.) (CVE-2009-4271)

It was discovered that the r8169 network driver did not
correctly check the size of Ethernet frames. A remote
attacker could send specially crafted traffic to crash the
system, leading to a denial of service. (CVE-2009-4537)

Wei Yongjun discovered that SCTP did not correctly validate
certain chunks. A remote attacker could send specially
crafted traffic to monopolize CPU resources, leading to a
denial of service. (Only affected Ubuntu 6.06 LTS.)
(CVE-2010-0008)

It was discovered that KVM did not correctly limit certain
privileged IO accesses on x86. Processes in the guest OS
with access to IO regions could gain further privileges
within the guest OS. (Did not affect Ubuntu 6.06 LTS.)
(CVE-2010-0298, CVE-2010-0306, CVE-2010-0419)

Evgeniy Polyakov discovered that IPv6 did not correctly
handle certain TUN packets. A remote attacker could exploit
this to crash the system, leading to a denial of service.
(Only affected Ubuntu 8.04 LTS.) (CVE-2010-0437)

Sachin Prabhu discovered that GFS2 did not correctly handle
certain locks. A local attacker with write access to a GFS2
filesystem could exploit this to crash the system, leading
to a denial of service. (CVE-2010-0727)

Jamie Strandboge discovered that network virtio in KVM did
not correctly handle certain high-traffic conditions. A
remote attacker could exploit this by sending specially
crafted traffic to a guest OS, causing the guest to crash,
leading to a denial of service. (Only affected Ubuntu 8.04
LTS.) (CVE-2010-0741)

Marcus Meissner discovered that the USB subsystem did not
correctly handle certain error conditions. A local attacker
with access to a USB device could exploit this to read
recently used kernel memory, leading to a loss of privacy
and potentially root privilege escalation. (CVE-2010-1083)

Neil Brown discovered that the Bluetooth subsystem did not
correctly handle large amounts of traffic. A physically
proximate remote attacker could exploit this by sending
specially crafted traffic that would consume all available
system memory, leading to a denial of service. (Ubuntu 6.06
LTS and 10.04 LTS were not affected.) (CVE-2010-1084)

Jody Bruchon discovered that the sound driver for the
AMD780V did not correctly handle certain conditions. A local
attacker with access to this hardward could exploit the flaw
to cause a system crash, leading to a denial of service.
(CVE-2010-1085)

Ang Way Chuang discovered that the DVB driver did not
correctly handle certain MPEG2-TS frames. An attacker could
exploit this by delivering specially crafted frames to
monopolize CPU resources, leading to a denial of service.
(Ubuntu 10.04 LTS was not affected.) (CVE-2010-1086)

Trond Myklebust discovered that NFS did not correctly handle
truncation under certain conditions. A local attacker with
write access to an NFS share could exploit this to crash the
system, leading to a denial of service. (Ubuntu 10.04 LTS
was not affected.) (CVE-2010-1087)

Al Viro discovered that automount of NFS did not correctly
handle symlinks under certain conditions. A local attacker
could exploit this to crash the system, leading to a denial
of service. (Ubuntu 6.06 LTS and Ubuntu 10.04 LTS were not
affected.) (CVE-2010-1088)

Matt McCutchen discovered that ReiserFS did not correctly
protect xattr files in the .reiserfs_priv directory. A local
attacker could exploit this to gain root privileges or crash
the system, leading to a denial of service. (CVE-2010-1146)

Eugene Teo discovered that CIFS did not correctly validate
arguments when creating new files. A local attacker could
exploit this to crash the system, leading to a denial of
service, or possibly gain root privileges if mmap_min_addr
was not set. (CVE-2010-1148)

Catalin Marinas and Tetsuo Handa discovered that the TTY
layer did not correctly release process IDs. A local
attacker could exploit this to consume kernel resources,
leading to a denial of service. (CVE-2010-1162)

Neil Horman discovered that TIPC did not correctly check its
internal state. A local attacker could send specially
crafted packets via AF_TIPC that would cause the system to
crash, leading to a denial of service. (Ubuntu 6.06 LTS was
not affected.) (CVE-2010-1187)

Masayuki Nakagawa discovered that IPv6 did not correctly
handle certain settings when listening. If a socket were
listening with the IPV6_RECVPKTINFO flag, a remote attacker
could send specially crafted traffic that would cause the
system to crash, leading to a denial of service. (Only
Ubuntu 6.06 LTS was affected.) (CVE-2010-1188)

Oleg Nesterov discovered that the Out-Of-Memory handler did
not correctly handle certain arrangements of processes. A
local attacker could exploit this to crash the system,
leading to a denial of service. (CVE-2010-1488).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."

"From Red Hat Security Advisory 2010:0146 :

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

The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

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 the sctp_rcv_ootb()
function in the Linux kernel Stream Control Transmission Protocol
(SCTP) implementation. A remote attacker could send a specially
crafted SCTP packet to a target system, resulting in a denial of
service. (CVE-2010-0008, Important)

* a NULL pointer dereference flaw was found in the Linux kernel.
During a core dump, the kernel did not check if the Virtual
Dynamically-linked Shared Object page was accessible. On Intel 64 and
AMD64 systems, a local, unprivileged user could use this flaw to cause
a kernel panic by running a crafted 32-bit application.
(CVE-2009-4271, Important)

* an information leak was found in the print_fatal_signal()
implementation in the Linux kernel. When
'/proc/sys/kernel/print-fatal-signals' is set to 1 (the default value
is 0), memory that is reachable by the kernel could be leaked to
user-space. This issue could also result in a system crash. Note that
this flaw only affected the i386 architecture. (CVE-2010-0003,
Moderate)

* on AMD64 systems, it was discovered that the kernel did not ensure
the ELF interpreter was available before making a call to the
SET_PERSONALITY macro. A local attacker could use this flaw to cause a
denial of service by running a 32-bit application that attempts to
execute a 64-bit application. (CVE-2010-0307, Moderate)

* missing capability checks were found in the ebtables implementation,
used for creating an Ethernet bridge firewall. This could allow a
local, unprivileged user to bypass intended capability restrictions
and modify ebtables rules. (CVE-2010-0007, Low)

This update also fixes the following bugs :

* under some circumstances, a locking bug could have caused an online
ext3 file system resize to deadlock, which may have, in turn, caused
the file system or the entire system to become unresponsive. In either
case, a reboot was required after the deadlock. With this update,
using resize2fs to perform an online resize of an ext3 file system
works as expected. (BZ#553135)

* some ATA and SCSI devices were not honoring the barrier=1 mount
option, which could result in data loss after a crash or power loss.
This update applies a patch to the Linux SCSI driver to ensure ordered
write caching. This solution does not provide cache flushes; however,
it does provide data integrity on devices that have no write caching
(or where write caching is disabled) and no command queuing. For
systems that have command queuing or write cache enabled there is no
guarantee of data integrity after a crash. (BZ#560563)

* it was found that lpfc_find_target() could loop continuously when
scanning a list of nodes due to a missing spinlock. This missing
spinlock allowed the list to be changed after the list_empty() test,
resulting in a NULL value, causing the loop. This update adds the
spinlock, resolving the issue. (BZ#561453)

* the fix for CVE-2009-4538 provided by RHSA-2010:0020 introduced a
regression, preventing Wake on LAN (WoL) working for network devices
using the Intel PRO/1000 Linux driver, e1000e. Attempting to configure
WoL for such devices resulted in the following error, even when
configuring valid options :

'Cannot set new wake-on-lan settings: Operation not supported not
setting wol'

This update resolves this regression, and WoL now works as expected
for network devices using the e1000e driver. (BZ#565496)

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."
