OpenAFS-SA-2013-0001: Buffer overflow in OpenAFS fileserver

By carefully crafting an ACL entry an attacker may overflow fixed length
buffers within the OpenAFS fileserver, crashing the fileserver, and
potentially permitting the execution of arbitrary code. To perform the
exploit, the attacker must already have permissions to create ACLs on the
fileserver in question.

Once such an ACL is present on a fileserver, client utilities such as 'fs'
which manipulate ACLs, may be crashed when they attempt to read or modify
the ACL.
