Synopsis
========

Multiple buffer overflow flaws and a parser error in LittleCMS could
cause Denial of Service.

Background
==========

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

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

——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 media-libs/lcms < 2.6-r1 >= 2.6-r1

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

Multiple stack-based buffer overflows and a profile parser error have
been found in LittleCMS.

Impact
======

A remote attacker could entice a user or automated system to open a
specially crafted file containing a malicious ICC profile, possibly
resulting in 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-2.6-r1”

Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying these packages.

NOTE: Gentoo has discontinued support for the LittleCMS 1.9 branch.
