Background ========== KPdf is a KDE-based PDF viewer included in the kdegraphics package. KWord is a KDE-based word processor also included in the koffice package. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 kde-base/kdegraphics < 3.4.3-r3 >= 3.4.3-r3 2 kde-base/kpdf < 3.4.3-r3 >= 3.4.3-r3 3 app-office/koffice < 1.4.2-r6 >= 1.4.2-r6 4 app-office/kword < 1.4.2-r6 >= 1.4.2-r6 ------------------------------------------------------------------- 4 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== KPdf and KWord both include Xpdf code to handle PDF files. This Xpdf code is vulnerable to several heap overflows (GLSA 200512-08) as well as several buffer and integer overflows discovered by Chris Evans. Impact ====== An attacker could entice a user to open a specially crafted PDF file with Kpdf or KWord, 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-r3" All Kpdf users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=kde-base/kpdf-3.4.3-r3" All KOffice users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-office/koffice-1.4.2-r6" All KWord users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-office/kword-1.4.2-r6" References ========== [ 1 ] CAN-2005-3191 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-3191 [ 2 ] CAN-2005-3192 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-3192 [ 3 ] CAN-2005-3193 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-3193 [ 4 ] CVE-2005-3624 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3624 [ 5 ] CVE-2005-3625 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3625 [ 6 ] CVE-2005-3626 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3626 [ 7 ] CVE-2005-3627 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3627 [ 8 ] GLSA 200512-08 http://www.gentoo.org/security/en/glsa/glsa-200512-08.xml [ 9 ] KDE Security Advisory: kpdf/xpdf multiple integer overflows http://www.kde.org/info/security/advisory-20051207-2.txt Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200601-02.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.
