Type: Security Advisory
Severity: Important
Issued on: 2005-07-06
Last updated on: 2005-07-06
Affected Products: Red Hat Desktop (v. 4)

CVEs (cve.mitre.org): CVE-2005-2096

Details

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
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.


Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
