CVE-2012-0870: Buffer Overflow
First published: Mon Feb 20 2012(Updated: )
A flaw was found in the way Samba handled Any Batched (AndX) request packets. A malicious request could cause smbd to enter an infinite recursion and overflow heap-based buffer during recursive calls. This can be triggered by an unauthenticated attacker, resulting in smbd child process crash or possibly code execution.
