Background ========== Adobe Reader (formerly Adobe Acrobat Reader) is a closed-source PDF reader. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/acroread < 8.1.4 >= 8.1.4 Description =========== Multiple vulnerabilities have been discovered in Adobe Reader: * Alin Rad Pop of Secunia Research reported a heap-based buffer overflow when processing PDF files containing a malformed JBIG2 symbol dictionary segment (CVE-2009-0193). * A buffer overflow related to a non-JavaScript function call and possibly an embedded JBIG2 image stream has been reported (CVE-2009-0658). * Tenable Network Security reported a stack-based buffer overflow that can be triggered via a crafted argument to the getIcon() method of a Collab object (CVE-2009-0927). * Sean Larsson of iDefense Labs reported a heap-based buffer overflow when processing a PDF file containing a JBIG2 stream with a size inconsistency related to an unspecified table (CVE-2009-0928). * Jonathan Brossard of the iViZ Security Research Team reported an unspecified vulnerability related to JBIG2 and input validation (CVE-2009-1061). * Will Dormann of CERT/CC reported a vulnerability lading to memory corruption related to JBIG2 (CVE-2009-1062). Impact ====== A remote attacker could entice a user to open a specially crafted PDF document, possibly leading to the execution of arbitrary code with the privileges of the user running the application, or a Denial of Service. Workaround ========== There is no known workaround at this time. Resolution ========== All Adobe Reader users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/acroread-8.1.4" References ========== [ 1 ] CVE-2009-0193 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0193 [ 2 ] CVE-2009-0658 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0658 [ 3 ] CVE-2009-0927 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0927 [ 4 ] CVE-2009-0928 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0928 [ 5 ] CVE-2009-1061 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1061 [ 6 ] CVE-2009-1062 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1062 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200904-17.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.
