Detailsinfo

A vulnerability, which was classified as problematic, was found in Linux Kernel (Operating System). Affected is the function handle_stop_signal of the file signal.c. The manipulation with an unknown input leads to a deadlock vulnerability. CWE is classifying the issue as CWE-833. The product contains multiple threads or executable segments that are waiting for each other to release a necessary lock, resulting in deadlock. This is going to have an impact on availability. CVE summarizes:

The handle_stop_signal function in signal.c in Linux kernel 2.6.11 up to other versions before 2.6.13 and 2.6.12.6 allows local users to cause a denial of service (deadlock) by sending a SIGKILL to a real-time threaded process while it is performing a core dump.

The issue has been introduced in 03/02/2005. The weakness was published 11/26/2005 with SuSE (Website). The advisory is shared for download at kernel.org. This vulnerability is traded as CVE-2005-3847. The exploitability is told to be difficult. The attack needs to be approached locally. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available.

The vulnerability was handled as a non-public zero-day exploit for at least 269 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 22559 (Debian DSA-1017-1 : kernel-source-2.6.8 - several vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks.

Upgrading to version 2.6.11 eliminates this vulnerability.
