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:
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"
