Synopsis
========
The pnmtopng utility, part of the Netpbm tools, contains a
vulnerability which can potentially result in the execution of
arbitrary code.
Background
==========
Netpbm is a package of 220 graphics programs and a programming library,
including pnmtopng, a tool to convert PNM image files to the PNG
format.
Affected packages
=================

Description
===========
RedHat reported that pnmtopng is vulnerable to a buffer overflow.
Impact
======
An attacker could craft a malicious PNM file and entice a user to run
pnmtopng on it, potentially resulting in the execution of arbitrary
code with the permissions of the user running pnmtopng.
Workaround
==========
There is no known workaround at this time.
