Background ========== Adobe Reader (formerly Adobe Acrobat Reader) is a closed-source PDF reader. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/acroread < 8.1.3 >= 8.1.3 Description =========== * An unspecified vulnerability can be triggered by a malformed PDF document, as demonstrated by 2008-HI2.pdf (CVE-2008-2549). * Peter Vreugdenhil, Dyon Balding, Will Dormann, Damian Frizza, and Greg MacManus reported a stack-based buffer overflow in the util.printf JavaScript function that incorrectly handles the format string argument (CVE-2008-2992). * Greg MacManus of iDefense Labs reported an array index error that can be leveraged for an out-of-bounds write, related to parsing of Type 1 fonts (CVE-2008-4812). * Javier Vicente Vallejo and Peter Vregdenhil, via Zero Day Initiative, reported multiple unspecified memory corruption vulnerabilities (CVE-2008-4813). * Thomas Garnier of SkyRecon Systems reported an unspecified vulnerability in a JavaScript method, related to an "input validation issue" (CVE-2008-4814). * Josh Bressers of Red Hat reported an untrusted search path vulnerability (CVE-2008-4815). * Peter Vreugdenhil reported through iDefense that the Download Manager can trigger a heap corruption via calls to the AcroJS function (CVE-2008-4817). Impact ====== A remote attacker could entice a user to open a specially crafted PDF document, and local attackers could entice a user to run acroread from an untrusted working directory. Both might result in 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-8.1.3" References ========== [ 1 ] CVE-2008-2549 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2549 [ 2 ] CVE-2008-2992 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2992 [ 3 ] CVE-2008-4812 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4812 [ 4 ] CVE-2008-4813 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4813 [ 5 ] CVE-2008-4814 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4814 [ 6 ] CVE-2008-4815 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4815 [ 7 ] CVE-2008-4817 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4817 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200901-09.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.
