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 ------------------------------------------------------------------- 1 media-libs/lcms < 2.6-r1 >= 2.6-r1 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.
