LittleCMS: Multiple vulnerabilities Multiple errors in LittleCMS allow for attacks including the remote execution of arbitrary code. littlecms April 19, 2009 April 19, 2009: 01 260269 264604 remote 1.18-r1 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"
