Background ========== KPdf is a KDE-based PDF viewer included in the kdegraphics package. KOffice is an integrated office suite for KDE. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-office/koffice < 1.3.5-r2 >= 1.3.5-r2 2 kde-base/kdegraphics < 3.3.2-r2 >= 3.3.2-r2 *>= 3.2.3-r4 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== KPdf and KOffice both include Xpdf code to handle PDF files. Xpdf is vulnerable to a new stack overflow, as described in GLSA 200501-28. Impact ====== An attacker could entice a user to open a specially-crafted PDF file, 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 KPdf users should upgrade to the latest version of kdegraphics: # emerge --sync # emerge --ask --oneshot --verbose kde-base/kdegraphics All KOffice users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose app-office/koffice References ========== [ 1 ] GLSA 200501-18 http://www.gentoo.org/security/en/glsa/glsa-200501-28.xml [ 2 ] CAN-2005-0064 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0064 [ 3 ] KDE Security Advisory: kpdf Buffer Overflow Vulnerability http://www.kde.org/info/security/advisory-20050119-1.txt [ 4 ] KDE Security Advisory: KOffice PDF Import Filter Vulnerability http://www.kde.org/info/security/advisory-20050120-1.txt Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200501-32.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.
