GLSA 201412-46: LittleCMS: Denial of Service

Severity:normal
Title:LittleCMS: Denial of Service
Date:12/26/2014
Bugs: #479874, #507788
ID:201412-46

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 Architecture(s)
media-libs/lcms < 2.6-r1 >= 2.6-r1 All supported architectures

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.
