CVE-2008-5029

Publication date 10 November 2008

Ubuntu priority

Medium

Why this priority?

The __scm_destroy function in net/core/scm.c in the Linux kernel 2.6.27.4, 2.6.26, and earlier makes indirect recursive calls to itself through calls to the fput function, which allows local users to cause a denial of service (panic) via vectors related to sending an SCM_RIGHTS message through a UNIX domain socket and closing file descriptors.

From the Ubuntu Security Team

It was discovered that the Unix Socket handler did not correctly process the SCM_RIGHTS message. A local attacker could make a malicious socket request that would crash the system, leading to a denial of service.
