RHEL 4 : zlib (RHSA-2005:569)

medium Nessus Plugin ID 18635

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-2005:569 advisory.

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 CAN-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.

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-2005:569.
