Reference: BUGTRAQ:20080409 IOActive Security Advisory: Buffer overflow in Python zlib extension module
Reference: URL:http://www.securityfocus.com/archive/1/archive/1/490690/100/0/threaded

Integer signedness error in the zlib extension module in Python 2.5.2
and earlier allows remote attackers to execute arbitrary code via a
negative signed integer, which triggers insufficient memory allocation
and a buffer overflow.
