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.
