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
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/netpbm < 10.29 >= 10.29
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.
Resolution
==========
All Netpbm users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/netpbm-10.29"
