Debian DSA-1588-1 : linux-2.6 - denial of service

high Nessus Plugin ID 32448
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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


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

- CVE-2007-6712 Johannes Bauer discovered an integer overflow condition in the hrtimer subsystem on 64-bit systems. This can be exploited by local users to trigger a denial of service (DoS) by causing the kernel to execute an infinite loop.

- CVE-2008-1615 Jan Kratochvil reported a local denial of service condition that permits local users on systems running the amd64 flavor kernel to cause a system crash.

- CVE-2008-2136 Paul Harks discovered a memory leak in the Simple Internet Transition (SIT) code used for IPv6 over IPv4 tunnels. This can be exploited by remote users to cause a denial of service condition.

- CVE-2008-2137 David Miller and Jan Lieskovsky discovered issues with the virtual address range checking of mmaped regions on the sparc architecture that may be exploited by local users to cause a denial of service.


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

For the stable distribution (etch), this problem has been fixed in version 2.6.18.dfsg.1-18etch5.

Builds for linux-2.6/s390 and fai-kernels/powerpc were not yet available at the time of this advisory. This advisory will be updated as these builds become available.
