Gentoo Linux Security Advisory GLSA 200904-19


                                        http://security.gentoo.org/

Severity: Normal
Title: LittleCMS: Multiple vulnerabilities
Date: April 19, 2009
Bugs: #260269, #264604
ID: 200904-19


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 &quot;&gt;=media-libs/lcms-1.18-r1&quot;
