CentOS 3 : netpbm (CESA-2005:843)

medium Nessus Plugin ID 21874

Synopsis

The remote CentOS host is missing one or more security updates.

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.

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.

Solution

Update the affected netpbm packages.
