Secunia

A vulnerability has been reported in the Linux Kernel, which can be exploited by malicious, local users to cause a DoS (Denial of Service).

The vulnerability is caused due to an error when setting the personality of a process, which can be exploited to cause a kernel crash by e.g. executing a 64bit application with a missing ELF interpreter out of a 32bit application and causing a segmentation fault.

Successful exploitation requires a 64bit system and may also require that core dumps are enabled.

Solution
Fixed in version 2.6.32.8.
