Background ========== Xpdf, Kpdf and GPdf are PDF file viewers that run under the X Window System. Kpdf and GPdf both contain Xpdf code. Kpdf is also part of kdegraphics. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/xpdf < 3.00-r10 >= 3.00-r10 2 kde-base/kdegraphics < 3.3.2-r3 >= 3.3.2-r3 3 kde-base/kpdf < 3.4.1-r1 >= 3.4.1-r1 4 app-text/gpdf < 2.10.0-r1 >= 2.10.0-r1 ------------------------------------------------------------------- 4 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== Xpdf, Kpdf and GPdf do not handle a broken table of embedded TrueType fonts correctly. After detecting such a table, Xpdf, Kpdf and GPdf attempt to reconstruct the information in it by decoding the PDF file, which causes the generation of a huge temporary file. Impact ====== A remote attacker may cause a Denial of Service by creating a specially crafted PDF file, sending it to a CUPS printing system (which uses Xpdf), or by enticing a user to open it in Xpdf, Kpdf, 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-r10" All GPdf users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/gpdf-2.10.0-r1" All Kpdf users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-3.3.2-r3" All KDE Split Ebuild Kpdf users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=kde-base/kpdf-3.4.1-r1" References ========== [ 1 ] CAN-2005-2097 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2097 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200508-08.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.
