linux-2.6 - privilege escalation

The vmsplice system call did not properly verify address arguments
passed by user space processes, which allowed local attackers to
overwrite arbitrary kernel memory, gaining root privileges
(CVE-2008-0010,
CVE-2008-0600).

In the vserver-enabled kernels, a missing access check on certain
symlinks in /proc enabled local attackers to access resources in other
vservers (CVE-2008-0163).

The old stable distribution (sarge) is not affected by this problem.

For the stable distribution (etch), this problem has been fixed in version
2.6.18.dfsg.1-18etch1.

In addition to these fixes, this update also incorporates changes from the
upcoming point release of the stable distribution.

Some architecture builds were not yet available at the time of DSA-1494-1.
This update to DSA-1494 provides linux-2.6 packages for these remaining
architectures, as well as additional binary packages that are built
from source code provided by linux-2.6.

The unstable (sid) and testing (lenny) distributions will be fixed soon.

We recommend that you upgrade your linux-2.6, fai-kernels, and
user-mode-linux packages.
