Debian Bug : 701744

Several vulnerabilities have been discovered in the Linux kernel that may lead
to a denial of service, information leak or privilege escalation. The Common
Vulnerabilities and Exposures project identifies the following problems:

CVE-2013-1059

Chanam Park reported an issue in the Ceph distributed storage system.
Remote users can cause a denial of service by sending a specially crafted
auth_reply message.

CVE-2013-2148

Dan Carpenter reported an information leak in the filesystem wide access
notification subsystem (fanotify). Local users could gain access to
sensitive kernel memory.

CVE-2013-2164

Jonathan Salwan reported an information leak in the CD-ROM driver. A
local user on a system with a malfunctioning CD-ROM drive could gain
access to sensitive memory.

CVE-2013-2232

Dave Jones and Hannes Frederic Sowa resolved an issue in the IPv6
subsystem. Local users could cause a denial of service by using an
AF_INET6 socket to connect to an IPv4 destination.

CVE-2013-2234

Mathias Krause reported a memory leak in the implementation of PF_KEYv2
sockets. Local users could gain access to sensitive kernel memory.

CVE-2013-2237

Nicolas Dichtel reported a memory leak in the implementation of PF_KEYv2
sockets. Local users could gain access to sensitive kernel memory.

CVE-2013-2851

Kees Cook reported an issue in the block subsystem. Local users with
uid 0 could gain elevated ring 0 privileges. This is only a security
issue for certain specially configured systems.

CVE-2013-2852

Kees Cook reported an issue in the b43 network driver for certain Broadcom
wireless devices. Local users with uid 0 could gain elevated ring 0
privileges. This is only a security issue for certain specially configured
systems.

CVE-2013-4162

Hannes Frederic Sowa reported an issue in the IPv6 networking subsystem.
Local users can cause a denial of service (system crash).

CVE-2013-4163

Dave Jones reported an issue in the IPv6 networking subsystem. Local
users can cause a denial of service (system crash).

This update also includes a fix for a regression in the Xen subsystem.

For the stable distribution (wheezy), these problems has been fixed in version
3.2.46-1+deb7u1.

The following matrix lists additional source packages that were rebuilt for
compatibility with or to take advantage of this update:

Debian 7.0 (wheezy)
user-mode-linux 3.2-2um-1+deb7u2

We recommend that you upgrade your linux and user-mode-linux packages.

Note: Debian carefully tracks all known security issues across every
linux kernel package in all releases under active security support.
However, given the high frequency at which low-severity security
issues are discovered in the kernel and the resource requirements of
doing an update, updates for lower priority issues will normally not
be released for all kernels at the same time. Rather, they will be
released in a staggered or "leap-frog" fashion.
