Little Color Management System (LittleCMS, or simply "lcms") is a small-footprint, speed-optimized open source color management engine.
Multiple integer overflow flaws which could lead to heap-based buffer overflows, as well as multiple insufficient input validation flaws, were found 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 by a victim. (CVE-2009-0723, CVE-2009-0733)
A memory leak flaw was found in LittleCMS. An application using LittleCMS could use excessive amount of memory, and possibly crash after using all available memory, if used to open specially-crafted images. (CVE-2009-0581)
Red Hat would like to thank Chris Evans from the Google Security Team for reporting these issues.
All users of LittleCMS should install these updated packages, which upgrade LittleCMS to version 1.18. All running applications using the lcms library must be restarted for the update to take effect.
