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

CVE-2009-2846

Michael Buesch noticed a typing issue in the eisa-eeprom driver
for the hppa architecture. Local users could exploit this issue to
gain access to restricted memory.

CVE-2009-2847

Ulrich Drepper noticed an issue in the do_sigalstack routine on
64-bit systems. This issue allows local users to gain access to
potentially sensitive memory on the kernel stack.

CVE-2009-2848

Eric Dumazet discovered an issue in the execve path, where the
clear_child_tid variable was not being properly cleared. Local
users could exploit this issue to cause a denial of service
(memory corruption).

CVE-2009-2849

Neil Brown discovered an issue in the sysfs interface to md
devices. When md arrays are not active, local users can exploit
this vulnerability to cause a denial of service (oops).

CVE-2009-2903

Mark Smith discovered a memory leak in the appletalk
implementation. When the appletalk and ipddp modules are loaded,
but no ipddp"N" device is found, remote attackers can cause a
denial of service by consuming large amounts of system memory.

CVE-2009-2908

Loic Minier discovered an issue in the eCryptfs filesystem. A
local user can cause a denial of service (kernel oops) by causing
a dentry value to go negative.

CVE-2009-2909

Arjan van de Ven discovered an issue in the AX.25 protocol
implementation. A specially crafted call to setsockopt() can
result in a denial of service (kernel oops).

CVE-2009-2910

Jan Beulich discovered the existence of a sensitive kernel memory
leak. Systems running the 'amd64' kernel do not properly sanitize
registers for 32-bit processes.

CVE-2009-3001

Jiri Slaby fixed a sensitive memory leak issue in the ANSI/IEEE
802.2 LLC implementation. This is not exploitable in the Debian
lenny kernel as root privileges are required to exploit this
issue.

CVE-2009-3002

Eric Dumazet fixed several sensitive memory leaks in the IrDA,
X.25 PLP (Rose), NET/ROM, Acorn Econet/AUN, and Controller Area
Network (CAN) implementations. Local users can exploit these
issues to gain access to kernel memory.

CVE-2009-3228

Eric Dumazet reported an instance of uninitialized kernel memory
in the network packet scheduler. Local users may be able to
exploit this issue to read the contents of sensitive kernel
memory.

CVE-2009-3238

Linus Torvalds provided a change to the get_random_int() function
to increase its randomness.

CVE-2009-3286

Eric Paris discovered an issue with the NFSv4 server
implementation. When an O_EXCL create fails, files may be left
with corrupted permissions, possibly granting unintentional
privileges to other local users.

CVE-2009-3547

Earl Chew discovered a NULL pointer dereference issue in the
pipe_rdwr_open function which can be used by local users to gain
elevated privileges.

CVE-2009-3612

Jiri Pirko discovered a typo in the initialization of a structure
in the netlink subsystem that may allow local users to gain access
to sensitive kernel memory.

CVE-2009-3613

Alistair Strachan reported an issue in the r8169 driver. Remote
users can cause a denial of service (IOMMU space exhaustion and
system crash) by transmitting a large amount of jumbo frames.

CVE-2009-3620

Ben Hutchings discovered an issue in the DRM manager for ATI Rage
128 graphics adapters. Local users may be able to exploit this
vulnerability to cause a denial of service (NULL pointer
dereference).

CVE-2009-3621

Tomoki Sekiyama discovered a deadlock condition in the UNIX domain
socket implementation. Local users can exploit this vulnerability
to cause a denial of service (system hang).

For the oldstable distribution (etch), this problem has been fixed in
version 2.6.24-6~etchnhalf.9etch1.

We recommend that you upgrade your linux-2.6.24 packages.

Note: Debian 'etch' includes linux kernel packages based upon both the
2.6.18 and 2.6.24 linux releases. All known security issues are
carefully tracked against both packages and both packages will receive
security updates until security support for Debian 'etch'
concludes. However, given the high frequency at which low-severity
security issues are discovered in the kernel and the resource
requirements of doing an update, lower severity 2.6.18 and 2.6.24
updates will typically release in a staggered or "leap-frog" fashion.

Upgrade instructions
- --------------------

wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
will update the internal database
apt-get upgrade
will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.

Debian GNU/Linux 4.0 alias etch
- -------------------------------

Oldstable updates are available for alpha, amd64, hppa, i386, ia64, and mipsel.
Updates for other architectures will be released as the they become available.
