Synopsis
========

A heap-based buffer overflow in LittleCMS might allow remote attackers
to execute arbitrary code.

Background
==========

LittleCMS, or short lcms, is a color management system for working with
ICC profiles. It is used by many applications including GIMP, Firefox
and Chromium.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/lcms < 2.10 >= 2.10

Description
===========

It was discovered that LittleCMS (aka Little Color Management System)
had an integer overflow in the AllocateDataSet function in cmscgats.c.

Impact
======

A remote attacker could entice a user or automated system to open a
specially crafted file containing malicious color data, possibly
resulting in execution of arbitrary code with the privileges of the
process or a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All LittleCMS users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/lcms-2.10"
