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

High Nessus Plugin ID 31028

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 8.9


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.
