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-r7 2 app-text/gpdf = 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 usersshould 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 https://www.cve.org/CVERecord?id=CVE-CAN-2004-1125 [ 2 ] iDEFENSE Advisory ;type=vulnerabilities&flashstatus=true Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200412-24 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.
