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

The vulnerability is caused due to a missing check of the thread's group ID in ptrace.c when trying to determine whether the process is attempting to attach to itself when CLONE_THREAD is used. This may be exploited to cause a kernel crash.

The vulnerability has been reported in versions prior to 2.6.14.2.

Solution:
Update to version 2.6.14.2 or later.
