Background ========== The JasPer Project is an open-source initiative to provide a free software-based reference implementation of the codec specified in the JPEG-2000 Part-1 (jpeg2k) standard. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/jasper < 1.900.1-r4 >= 1.900.1-r4 Description =========== Two vulnerabilities have been found in JasPer: * The jpc_cox_getcompparms function in libjasper/jpc/jpc_cs.c contains an error that could overwrite certain callback pointers, possibly causing a heap-based buffer overflow (CVE-2011-4516). * The jpc_crg_getparms function in libjasper/jpc/jpc_cs.c uses an incorrect data type, possibly causing a heap-based buffer overflow (CVE-2011-4517). Impact ====== A remote attacker could entice a user or automated system to process specially crafted JPEG-2000 files with an application using JasPer, possibly resulting in the execution of arbitrary code with the privileges of the application, or a Denial of Service. Workaround ========== There is no known workaround at this time. Resolution ========== All JasPer users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/jasper-1.900.1-r4" References ========== [ 1 ] CVE-2011-4516 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-4516 [ 2 ] CVE-2011-4517 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-4517 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201201-10.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.
