Gentoo Linux Security Advisory

Title: LittleCMS: Multiple vulnerabilities (GLSA 200904-19)
Severity: normal
Exploitable: remote
Date: April 19, 2009
Bug(s): #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: media-libs/lcms
Vulnerable: < 1.18-r1
Unaffected: >= 1.18-r1
Architectures: All supported architectures


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:
