Title:RHSA-2005:584: zlib security update (Important)
Description:Zlib is a general-purpose lossless data compression library that is used by many different programs.

A previous zlib update, RHSA-2005:569 (CAN-2005-2096) fixed a flaw in zlib that could allow a carefully crafted compressed stream to crash an application. While the original patch corrected the reported overflow, Markus Oberhumer discovered additional ways a stream could trigger an overflow. An attacker could create a carefully crafted compressed stream that would cause an application to crash if the stream is opened by a user. As an example, an attacker could create a malicious PNG image file that would cause a Web browser or mail viewer to crash if the image is viewed. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CAN-2005-1849 to this issue.

Note that the versions of zlib shipped with Red Hat Enterprise Linux 2.1 and 3 are not vulnerable to this issue.

All users should update to these errata packages that contain a patch from Mark Adler that corrects this issue.
