Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
Multiple errors in LittleCMS allow for attacks including the remote
execution of arbitrary code.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
-------------------------------------------------------------------

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
RedHat reported a null-pointer dereference flaw while processing
monochrome ICC profiles (CVE-2009-0793).
Chris Evans of Google discovered the following vulnerabilities:
* LittleCMS contains severe memory leaks (CVE-2009-0581).
* LittleCMS is prone to multiple integer overflows, leading to a
heap-based buffer overflow (CVE-2009-0723).
* The ReadSetOfCurves() function is vulnerable to stack-based buffer
overflows when called from code paths without a bounds check on
channel counts (CVE-2009-0733).
Impact
=3D=3D=3D=3D=3D=3D
A remote attacker could entice a user or automated system to open a
specially crafted file containing a malicious ICC profile, possibly
resulting in the execution of arbitrary code with the privileges of the
user running the application or memory exhaustion, leading to a Denial
of Service condition.
Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
All LittleCMS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dmedia-libs/lcms-1.18-r1"
