CERT Advisory CA-2002-07 - A bug in the zlib compression library prior to v1.1.4 manifests itself as a vulnerability in any of the many programs that are linked with zlib, and allows an attackers to mount a dos attack, gather info, or execute arbitrary code. Passing a specially-crafted block of invalid compressed data to a program that includes zlib, the program's attempt to decompress the crafted data can cause the zlib routines to corrupt the internal data structures. Fix available here.
