                   Red Hat Security Advisory

Synopsis:          Moderate: netpbm security update
Advisory ID:       RHSA-2005:793-01
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2005-793.html
Issue date:        2005-10-18
Updated on:        2005-10-18
Product:           Red Hat Enterprise Linux
CVE Names:         CAN-2005-2978
- ---------------------------------------------------------------------

1. Summary:

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Problem description:

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 CAN-2005-2978 to this issue.

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

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.
