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 of the 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 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0581 [ 2 ] CVE-2009-0723 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0723 [ 3 ] CVE-2009-0733 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0733 [ 4 ] CVE-2009-0793 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0793 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200904-19.xml 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.
