Gentoo: GLSA-200901-09 Normal: Adobe Reader Arbitrary Code Execution

Adobe Reader is vulnerable to execution of arbitrary code.. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 200901-09 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: Adobe Reader: User-assisted execution of arbitrary code Date: January 13, 2009 Bugs: #225483 ID: 200901-09 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======= Adobe Reader is vulnerable to execution of arbitrary code. 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 Bressersof 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 https://www.cve.org/CVERecord?id=CVE-2008-2549 [ 2 ] CVE-2008-2992 https://www.cve.org/CVERecord?id=CVE-2008-2992 [ 3 ] CVE-2008-4812 https://www.cve.org/CVERecord?id=CVE-2008-4812 [ 4 ] CVE-2008-4813 https://www.cve.org/CVERecord?id=CVE-2008-4813 [ 5 ] CVE-2008-4814 https://www.cve.org/CVERecord?id=CVE-2008-4814 [ 6 ] CVE-2008-4815 https://www.cve.org/CVERecord?id=CVE-2008-4815 [ 7 ] CVE-2008-4817 https://www.cve.org/CVERecord?id=CVE-2008-4817 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200901-09 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.
