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-r3 >= 1.900.1-r3 Description =========== Marc Espie and Christian Weisgerber have discovered multiple vulnerabilities in JasPer: * Multiple integer overflows might allow for insufficient memory allocation, leading to heap-based buffer overflows (CVE-2008-3520). * The jas_stream_printf() function in libjasper/base/jas_stream.c uses vsprintf() to write user-provided data to a static to a buffer, leading to an overflow (CVE-2008-3522). Impact ====== Remote attackers could entice a user or automated system to process specially crafted jpeg2k files with an application using JasPer, possibly leading to the execution of arbitrary code. 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-r3" References ========== [ 1 ] CVE-2008-3520 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-3520 [ 2 ] CVE-2008-3522 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-3522 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200812-18.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.
