RHEL 4 : netpbm (RHSA-2005:793)

This script is Copyright (C) 2005-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated netpbm packages that fix a security issue 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, including .pbm
(portable bitmaps), .pgm (portable graymaps), .pnm (portable anymaps),
.ppm (portable pixmaps) and others.

A bug was found in the way netpbm converts Portable Anymap (PNM) files
into Portable Network Graphics (PNG). The usage of uninitialised
variables in the pnmtopng code allows an attacker to change stack
contents when converting to PNG files with pnmtopng using the '-trans'
option. This may allow an attacker to execute arbitrary code. The
Common Vulnerabilities and Exposures project assigned the name
CVE-2005-2978 to this issue.

All users of netpbm should upgrade to the updated packages, which
contain a backported patch to resolve this issue.
