Background ========== Xpdf is a PDF file viewer that runs under the X Window System. Poppler is a PDF rendering library based on the Xpdf 3.0 code base. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/xpdf < 3.01-r7 >= 3.01-r7 2 app-text/poppler < 0.5.0-r4 >= 0.5.0-r4 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== Dirk Mueller has reported a vulnerability in Xpdf. It is caused by a missing boundary check in the splash rasterizer engine when handling PDF splash images with overly large dimensions. Impact ====== By sending a specially crafted PDF file to a victim, an attacker could cause an overflow, potentially resulting in the execution of arbitrary code with the privileges of the user running the application. 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-3.01-r7" All Poppler users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/poppler-0.5.0-r4" References ========== [ 1 ] CVE-2006-0301 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0301 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200602-04.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.
