Synopsis

========

 

Multiple errors in LittleCMS allow for attacks including the remote

execution of 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 and

Firefox.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 media-libs/lcms < 1.18-r1 >= 1.18-r1

 

Description

===========

 

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

======

 

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

==========

 

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-1.18-r1"
