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

This script is Copyright (C) 2013 Tenable Network Security, Inc.


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.
