1. Summary:

Updated kernel packages that fix two security issues and three bugs are now
available for Red Hat Enterprise Linux 6.5 Extended Update Support.

Red Hat Product Security 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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Compute Node Optional EUS (v. 6.5) - x86_64
Red Hat Enterprise Linux HPC Node EUS (v. 6.5) - noarch, x86_64
Red Hat Enterprise Linux Server EUS (v. 6.5) - i386, noarch, ppc64, s390x, x86_64
Red Hat Enterprise Linux Server Optional EUS (v. 6.5) - i386, ppc64, s390x, x86_64

3. Description:

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

* It was found that the Linux kernel's implementation of vectored pipe read
and write functionality did not take into account the I/O vectors that were
already processed when retrying after a failed atomic access operation,
potentially resulting in memory corruption due to an I/O vector array
overrun. A local, unprivileged user could use this flaw to crash the system
or, potentially, escalate their privileges on the system. (CVE-2015-1805,
Important)

* A buffer overflow flaw was found in the way the Linux kernel's Intel
AES-NI instructions optimized version of the RFC4106 GCM mode decryption
functionality handled fragmented packets. A remote attacker could use this
flaw to crash, or potentially escalate their privileges on, a system over a
connection with an active AES-GCM mode IPSec security association.
(CVE-2015-3331, Important)

The security impact of the CVE-2015-1805 issue was discovered by Red Hat.

This update also fixes the following bugs:

* Parallel extending direct I/O writes to a file could previously race to
update the size of the file. If executed in an incorrect order, the file
size could move backwards and push a previously completed write beyond the
end of the file, which resulted in losing the write. With this update, file
size updates always execute in appropriate order, thus fixing this bug.
(BZ#1218498) 

* When the load rose and run queues were busy due to the effects of the
enqueue_entity() function, tasks with large sched_entity.vruntime values
could previously be prevented from using the CPU time. A patch eliminating
the entity_key() function in the sched_fair.c latency value has been
backported from upstream, and all tasks are now provided with fair CPU
runtime. (BZ#1219121) 

* Previously, running the clock_gettime() function quickly in a loop could
result in a jump back in time. Consequently, programs could behave
unexpectedly when they assumed that clock_getime() returned an equal or
greater time in subsequent calls. With this update, if the time delta
between calls is negative, the clock is no longer updated. As a result, a
subsequent call to clock_gettime() is guaranteed to return a time greater
than or equal to a previous call. (BZ#1219500)

All kernel users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. The system must be
rebooted for this update to take effect.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

Red Hat 6.5 RHSA-2015:1199-01 Critical: Kernel Memory Corruption Alert

red hat

June 30, 2015

Updated kernel packages that fix two security issues and three bugs are now available for Red Hat Enterprise Linux 6.5 Extended Update Support

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.
