LittleCMS: Multiple vulnerabilities — GLSA 200904-19

Multiple errors in LittleCMS allow for attacks including the remote execution of arbitrary code.

Affected Packages

media-libs/lcms on all architectures
Affected versions < 1.18-r1
Unaffected versions >= 1.18-r1


LittleCMS, or short lcms, is a color management system for working with ICC profiles. It is used by many applications including GIMP and Firefox.


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).


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.


There is no known workaround at this time.


All LittleCMS users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-libs/lcms-1.18-r1"
