3. Description:
Little Color Management System (LittleCMS, or simply “lcms”) is a
small-footprint, speed-optimized open source color management engine.
Multiple insufficient input validation flaws were discovered in LittleCMS.
An attacker could use these flaws to create a specially-crafted image file
which could cause an application using LittleCMS to crash, or, possibly,
execute arbitrary code when opened. (CVE-2008-5316, CVE-2008-5317)
Users of lcms should upgrade to these updated packages, which contain
backported patches to correct these issues. All running applications using
lcms library must be restarted for the update to take effect.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259
