Detail

Problem Description:

Updated netpbm packages that fix two security issues are now available.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux WS version 2.1 - i386 Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

3. Problem description:

The netpbm package contains a library of functions that support programs for handling various graphics file formats.

A stack based buffer overflow bug was found in the way netpbm converts Portable Anymap (PNM) files into Portable Network Graphics (PNG). A specially crafted PNM file could allow an attacker to execute arbitrary code by attempting to convert a PNM file to a PNG file when using pnmtopng with the '-text' option. The Common Vulnerabilities and Exposures project has assigned the name CVE-2005-3632 to this issue.

An "off by one" bug was found in the way netpbm converts Portable Anymap (PNM) files into Portable Network Graphics (PNG). If a victim attempts to convert a specially crafted 256 color PNM file to a PNG file, then it can cause the pnmtopng utility to crash. The Common Vulnerabilities and Exposures project has assigned the name CVE-2005-3662 to this issue.

All users of netpbm should upgrade to these updated packages, which contain backported patches that resolve these issues.

4. 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.
