Debian Bug(s) :

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

CVE-2010-3875

Vasiliy Kulikov discovered an issue in the Linux implementation of the
Amateur Radio AX.25 Level 2 protocol. Local users may obtain access to
sensitive kernel memory.

CVE-2011-0695

Jens Kuehnel reported an issue in the InfiniBand stack. Remote attackers can
exploit a race condition to cause a denial of service (kernel panic).

CVE-2011-0711

Dan Rosenberg reported an issue in the XFS filesystem. Local users may
obtain access to sensitive kernel memory.

CVE-2011-0726

Kees Cook reported an issue in the /proc/pid/stat implementation. Local
users could learn the text location of a process, defeating protections
provided by address space layout randomization (ASLR).

CVE-2011-1016

Marek Olšák discovered an issue in the driver for ATI/AMD Radeon video
chips. Local users could pass arbitrary values to video memory and the
graphics translation table, resulting in denial of service or escalated
privileges. On default Debian installations, this is exploitable only by
members of the 'video' group.

CVE-2011-1078

Vasiliy Kulikov discovered an issue in the Bluetooth subsystem. Local users
can obtain access to sensitive kernel memory.

CVE-2011-1079

Vasiliy Kulikov discovered an issue in the Bluetooth subsystem. Local users
with the CAP_NET_ADMIN capability can cause a denial of service (kernel
Oops).

CVE-2011-1080

Vasiliy Kulikov discovered an issue in the Netfilter subsystem. Local users
can obtain access to sensitive kernel memory.

CVE-2011-1090

Neil Horman discovered a memory leak in the setacl() call on NFSv4
filesystems. Local users can explot this to cause a denial of service
(Oops).

CVE-2011-1160

Peter Huewe reported an issue in the Linux kernel's support for TPM security
chips. Local users with permission to open the device can gain access to
sensitive kernel memory.

CVE-2011-1163

Timo Warns reported an issue in the kernel support for Alpha OSF format disk
partitions. Users with physical access can gain access to sensitive kernel
memory by adding a storage device with a specially crafted OSF partition.

CVE-2011-1170

Vasiliy Kulikov reported an issue in the Netfilter arp table
implementation. Local users with the CAP_NET_ADMIN capability can gain
access to sensitive kernel memory.

CVE-2011-1171

Vasiliy Kulikov reported an issue in the Netfilter IP table
implementation. Local users with the CAP_NET_ADMIN capability can gain
access to sensitive kernel memory.

CVE-2011-1172

Vasiliy Kulikov reported an issue in the Netfilter IP6 table
implementation. Local users with the CAP_NET_ADMIN capability can gain
access to sensitive kernel memory.

CVE-2011-1173

Vasiliy Kulikov reported an issue in the Acorn Econet protocol
implementation. Local users can obtain access to sensitive kernel memory on
systems that use this rare hardware.

CVE-2011-1180

Dan Rosenberg reported a buffer overflow in the Information Access Service
of the IrDA protocol, used for Infrared devices. Remote attackers within IR
device range can cause a denial of service or possibly gain elevated
privileges.

CVE-2011-1182

Julien Tinnes reported an issue in the rt_sigqueueinfo interface. Local
users can generate signals with falsified source pid and uid information.

CVE-2011-1476

Dan Rosenberg reported issues in the Open Sound System MIDI interface that
allow local users to cause a denial of service. This issue does not affect
official Debian Linux image packages as they no longer provide support for
OSS. However, custom kernels built from Debians linux-source-2.6.32 may
have enabled this configuration and would therefore be vulnerable.

CVE-2011-1477

Dan Rosenberg reported issues in the Open Sound System driver for cards that
include a Yamaha FM synthesizer chip. Local users can cause memory
corruption resulting in a denial of service. This issue does not affect
official Debian Linux image packages as they no longer provide support for
OSS. However, custom kernels built from Debians linux-source-2.6.32 may
have enabled this configuration and would therefore be vulnerable.

CVE-2011-1478

Ryan Sweat reported an issue in the Generic Receive Offload (GRO) support in
the Linux networking subsystem. If an interface has GRO enabled and is
running in promiscuous mode, remote users can cause a denial of service
(NULL pointer dereference) by sending packets on an unknown VLAN.

CVE-2011-1493

Dan Rosenburg reported two issues in the Linux implementation of the Amateur
