GPdf includes Xpdf code and therefore is vulnerable to the same issues. Background ========== Xpdf is an open source viewer for Portable Document Format (PDF) files. GPdf is a Gnome-based PDF viewer that includes some Xpdf code. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/xpdf <= 3.00-r6 >= 3.00-r7 2 app-text/gpdf <= 2.8.1 >= 2.8.1-r1 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== A new integer overflow issue was discovered in Xpdf's Gfx::doImage() function. Impact ====== An attacker could entice an user to open a specially-crafted PDF file, potentially resulting in execution of arbitrary code with the rights of the user running Xpdf or GPdf. Workaround ========== There is no known workaround at this time. Resolution ========== All Xpdf users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/xpdf-3.00-r7" All GPdf users should also upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/gpdf-2.8.1-r1" References ========== [ 1 ] CAN-2004-1125 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-1125 [ 2 ] iDEFENSE Advisory http://www.idefense.com/application/poi/display?id=172&type=vulnerabilities&flashstatus=true Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200412-24.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.
