Background ========== KPdf is a KDE-based PDF viewer included in the kdegraphics package. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 kde-base/kdegraphics < 3.4.3-r4 >= 3.4.3-r4 2 kde-base/kpdf < 3.4.3-r4 >= 3.4.3-r4 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== KPdf includes Xpdf code to handle PDF files. Dirk Mueller discovered that the Xpdf code is vulnerable a heap based overflow in the splash rasterizer engine. Impact ====== An attacker could entice a user to open a specially crafted PDF file with Kpdf, potentially resulting in the execution of arbitrary code with the rights of the user running the affected application. Workaround ========== There is no known workaround at this time. Resolution ========== All kdegraphics users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-3.4.3-r4" All Kpdf users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=kde-base/kpdf-3.4.3-r4" References ========== [ 1 ] CVE-2006-0301 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0301 [ 2 ] KDE Security Advisory: kpdf/xpdf heap based buffer overflow http://www.kde.org/info/security/advisory-20060202-1.txt Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200602-05.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.
