Description:
Paul Starzetz and Wojciech Purczynski have reported a vulnerability in the Linux kernel, which can be exploited by malicious, local users to escalate their privileges.
The vulnerability is caused due to a boundary error in the "mremap()" system call. This may lead to the creation of a 0 bytes virtual memory area (VMA), which disrupts kernel memory management.
Successful exploitation allows execution of arbitrary code with kernel level privileges.
The vulnerability has been reported in the 2.4 and 2.6 series.
