The remote Red Hat host is missing one or more security updates.
Updated Zlib packages that fix a buffer overflow are now available for
Red Hat Enterprise Linux 4.
This update has been rated as having important security impact by the
Red Hat Security Response Team.
Zlib is a general-purpose lossless data compression library which is
used by many different programs.
Tavis Ormandy discovered a buffer overflow affecting Zlib version 1.2
and above. 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 which would cause a web browser or mail viewer to crash
if the image is viewed. The Common Vulnerabilities and Exposures
project assigned the name CVE-2005-2096 to this issue.
Please note that the versions of Zlib as shipped with Red Hat
Enterprise Linux 2.1 and 3 are not vulnerable to this issue.
All users should update to these erratum packages which contain a
patch from Mark Adler which corrects this issue.
