Synopsis
========
A vulnerability in CUPS might allow for the execution of arbitrary code
or a Denial of Service.

Background
==========
CUPS provides a portable printing layer for UNIX-based operating
systems.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-print/cups < 1.2.12-r8 >= 1.2.12-r8=

Description
===========
Thomas Pollet reported a possible integer overflow vulnerability in the
PNG image handling in the file filter/image-png.c.

Impact
======
A malicious user might be able to execute arbitrary code with the
privileges of the user running CUPS (usually lp), or cause a Denial of
Service by sending a specially crafted PNG image to the print server.
The vulnerability is exploitable via the network if CUPS is sharing
printers remotely.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All CUPS users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-print/cups-1.2.12-r8"
