Vulnerability Assessment Details

RHSA-2005-793: netpbm

Vulnerability Assessment Summary
Check for the version of the netpbm packages

Detailed Explanation for this Vulnerability Assessment

Updated netpbm packages that fix a security issue are now available.

This update has been rated as having moderate security impact by the Red
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 permits a possible hacker to change stack contents when
converting to PNG files with pnmtopng using the '-trans' option. This may
permit a possible hacker 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.
