Description: Two vulnerabilities have been reported in Sophos Anti-Virus, which can be exploited by malicious people to compromise a user's system. 1) A boundary error in veex.dll when processing CPIO archives can be exploited to cause a stack-based buffer overflow via a CPIO archive containing an overly long, non-NULL terminated filename. 2) A boundary error in veex.dll when parsing SIT archives can be exploited to cause a heap-based buffer overflow via a SIT archive containing a file with an overly long, non-NULL terminated filename. Successful exploitation of the vulnerabilities allows execution of arbitrary code. Solution: Update to version 2.40 of the scanning engine. Provided and/or discovered by: Discovered by an anonymous person and reported via ZDI.
