Debian DSA-1494-2 : linux-2.6 - missing access checks

High Nessus Plugin ID 31028


The remote Debian host is missing a security-related update.


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 ).


Upgrade the linux-2.6, fai-kernels, and user-mode-linux packages.

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.
