Permissions, Privileges, and Access Controls in Linux kernel - CVE-2013-1979

Vulnerability details

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The scm_set_cred function in include/net/scm.h in the Linux kernel before 3.8.11 uses incorrect uid and gid values during credentials passing, which allows local users to gain privileges via a crafted application.
