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 < 1.18-r1 > = 1.18-r1 Description ========== RedHat reported a null-pointer dereference flaw while processing monochrome ICC profiles (CVE-2009-0793). Chris Evans of Google discovered the following vulnerabilities: * LittleCMS contains severe memory leaks (CVE-2009-0581). * LittleCMS is prone to multiple integer overflows, leading to a heap-based buffer overflow (CVE-2009-0723). * The ReadSetOfCurves() function is vulnerable to stack-based buffer overflows when called from code paths without a bounds check on channel counts (CVE-2009-0733). 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 the execution of arbitrary code with the privileges ofthe user running the application or memory exhaustion, leading to 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-1.18-r1" References ========= [ 1 ] CVE-2009-0581 https://www.cve.org/CVERecord?id=CVE-2009-0581 [ 2 ] CVE-2009-0723 https://www.cve.org/CVERecord?id=CVE-2009-0723 [ 3 ] CVE-2009-0733 https://www.cve.org/CVERecord?id=CVE-2009-0733 [ 4 ] CVE-2009-0793 https://www.cve.org/CVERecord?id=CVE-2009-0793 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200904-19 Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
