CVE-2009-1439

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

CVE-2009-0028

Chris Evans discovered a situation in which a child process can
send an arbitrary signal to its parent.

CVE-2009-0834

Roland McGrath discovered an issue on amd64 kernels that allows
local users to circumvent system call audit configurations which
filter based on the syscall numbers or argument details.

CVE-2009-0835

Roland McGrath discovered an issue on amd64 kernels with
CONFIG_SECCOMP enabled. By making a specially crafted syscall,
local users can bypass access restrictions.

CVE-2009-0859

Jiri Olsa discovered that a local user can cause a denial of
service (system hang) using a SHM_INFO shmctl call on kernels
compiled with CONFIG_SHMEM disabled. This issue does not affect
prebuilt Debian kernels.

CVE-2009-1046

Mikulas Patocka reported an issue in the console subsystem that
allows a local user to cause memory corruption by selecting a
small number of 3-byte UTF-8 characters.

CVE-2009-1072

Igor Zhbanov reported that nfsd was not properly dropping
CAP_MKNOD, allowing users to create device nodes on file systems
exported with root_squash.

CVE-2009-1184

Dan Carpenter reported a coding issue in the selinux subsystem
that allows local users to bypass certain networking checks when
running with compat_net=1.

CVE-2009-1192

Shaohua Li reported an issue in the AGP subsystem they may allow
local users to read sensitive kernel memory due to a leak of
uninitialized memory.

CVE-2009-1242

Benjamin Gilbert reported a local denial of service vulnerability
in the KVM VMX implementation that allows local users to trigger
an oops.

CVE-2009-1265

Thomas Pollet reported an overflow in the af_rose implementation
that allows remote attackers to retrieve uninitialized kernel
memory that may contain sensitive data.

CVE-2009-1337

Oleg Nesterov discovered an issue in the exit_notify function that
allows local users to send an arbitrary signal to a process by
running a program that modifies the exit_signal field and then
uses an exec system call to launch a setuid application.

CVE-2009-1338

Daniel Hokka Zakrisson discovered that a kill(-1) is permitted to
reach processes outside of the current process namespace.

CVE-2009-1439

Pavan Naregundi reported an issue in the CIFS filesystem code that
allows remote users to overwrite memory via a long
nativeFileSystem field in a Tree Connect response during mount.

For the stable distribution (lenny), these problems have been fixed in
version 2.6.26-15lenny2.

For the oldstable distribution (etch), these problems, where applicable,
will be fixed in future updates to linux-2.6 and linux-2.6.24.

We recommend that you upgrade your linux-2.6 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.

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

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

Debian 5.0 (lenny)
user-mode-linux 2.6.26-1um-2+15lenny2

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

Debian GNU/Linux 5.0 alias lenny
- --------------------------------

Stable updates are available for alpha, amd64, arm, armel, hppa, i386, ia64, mips, mipsel, powerpc, s390 and sparc.
