Description:
Paul Starzetz has reported a vulnerability in the Linux kernel, which can be exploited by malicious, local users to gain escalated privileges.
The vulnerability is caused due to a race condition in the page fault handler when two threads, which share the same virtual memory space, request a stack expansion simultaneously.
Successful exploitation may allow execution of arbitrary code with root privileges on multi-processor systems.
The vulnerability has been reported in versions 2.4 through 2.4.29-rc1 and 2.6 through 2.6.10.
