Synopsis: Important: kernel security and bug fix update
Advisory ID: SLSA-2013:1173-1
Issue Date: 2013-08-27
CVE Numbers: CVE-2012-6544
CVE-2013-2206
CVE-2013-2224
CVE-2013-2237
CVE-2013-2232
CVE-2013-2146

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.
