Scientific Linux Security Update : kernel on SL6.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

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

This update fixes the following security issues :

- An integer overflow flaw was found in the
i915_gem_do_execbuffer() function in the Intel i915
driver in the Linux kernel. A local, unprivileged user
could use this flaw to cause a denial of service. This
issue only affected 32-bit systems. (CVE-2012-2384,
Moderate)

- A memory leak flaw was found in the way the Linux
kernel's memory subsystem handled resource clean up in
the mmap() failure path when the MAP_HUGETLB flag was
set. A local, unprivileged user could use this flaw to
cause a denial of service. (CVE-2012-2390, Moderate)

- A race condition was found in the way access to
inet->opt ip_options was synchronized in the Linux
kernel's TCP/IP protocol suite implementation. Depending
on the network facing applications running on the
system, a remote attacker could possibly trigger this
flaw to cause a denial of service. A local, unprivileged
user could use this flaw to cause a denial of service
regardless of the applications the system runs.
(CVE-2012-3552, Moderate)

- A flaw was found in the way the Linux kernel's dl2k
driver, used by certain D-Link Gigabit Ethernet
adapters, restricted IOCTLs. A local, unprivileged user
could use this flaw to issue potentially harmful IOCTLs,
which could cause Ethernet adapters using the dl2k
driver to malfunction (for example, losing network
connectivity). (CVE-2012-2313, Low)

- A flaw was found in the way the msg_namelen variable in
the rds_recvmsg() function of the Linux kernel's
Reliable Datagram Sockets (RDS) protocol implementation
was initialized. A local, unprivileged user could use
this flaw to leak kernel stack memory to user-space.
(CVE-2012-3430, Low)

This update also fixes several bugs.

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