RHEL 4 : zlib (RHSA-2005:584)

high Nessus Plugin ID 19284

Synopsis

The remote Red Hat host is missing a security update for zlib.

Description

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2005:584 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL zlib package based on the guidance in RHSA-2005:584.
