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

Medium Nessus Plugin ID 62346

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.

Solution

Update the affected packages.
