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

Medium Nessus Plugin ID 69503

Synopsis

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

Description

This update fixes the following security issues :

- A flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled duplicate cookies. If a local user queried SCTP connection information at the same time a remote attacker has initialized a crafted SCTP connection to the system, it could trigger a NULL pointer dereference, causing the system to crash. (CVE-2013-2206, Important)

- It was found that the fix for CVE-2012-3552 released via SLSA-2012:1304 introduced an invalid free flaw in the Linux kernel's TCP/IP protocol suite implementation. A local, unprivileged user could use this flaw to corrupt kernel memory via crafted sendmsg() calls, allowing them to cause a denial of service or, potentially, escalate their privileges on the system. (CVE-2013-2224, Important)

- A flaw was found in the Linux kernel's Performance Events implementation. On systems with certain Intel processors, a local, unprivileged user could use this flaw to cause a denial of service by leveraging the perf subsystem to write into the reserved bits of the OFFCORE_RSP_0 and OFFCORE_RSP_1 model-specific registers. (CVE-2013-2146, Moderate)

- An invalid pointer dereference flaw was found in the Linux kernel's TCP/IP protocol suite implementation. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system by using sendmsg() with an IPv6 socket connected to an IPv4 destination. (CVE-2013-2232, Moderate)

- Information leak flaws in the Linux kernel's Bluetooth implementation could allow a local, unprivileged user to leak kernel memory to user- space. (CVE-2012-6544, Low)

- An information leak flaw in the Linux kernel could allow a privileged, local user to leak kernel memory to user-space. (CVE-2013-2237, Low)

The system must be rebooted for this update to take effect.

Solution

Update the affected packages.
