Background ========== GPdf is a Gnome-based PDF viewer. KPDF, part of the kdegraphics package, is a KDE-based PDF viewer. KOffice is an integrated office suite for KDE. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-office/koffice < 1.3.3-r1 >= 1.3.3-r1 2 app-text/gpdf < 2.8.0-r1 >= 2.8.0-r1 *>= 0.132-r1 3 kde-base/kdegraphics < 3.3.1-r1 >= 3.3.1-r1 *>= 3.3.0-r1 *>= 3.2.3-r1 ------------------------------------------------------------------- 3 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== GPdf, KPDF and KOffice all include xpdf code to handle PDF files. xpdf is vulnerable to multiple integer overflows, as described in GLSA 200410-20. Impact ====== An attacker could entice a user to open a specially-crafted PDF file, potentially resulting in execution of arbitrary code with the rights of the user running the affected utility. Workaround ========== There is no known workaround at this time. Resolution ========== All GPdf users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/gpdf-0.132-r1" All KDE users should upgrade to the latest version of kdegraphics: # emerge --sync # emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-3.3.0-r1" All KOffice users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-office/koffice-1.3.3-r1" References ========== [ 1 ] GLSA 200410-20 http://www.gentoo.org/security/en/glsa/glsa-200410-20.xml [ 2 ] CAN-2004-0888 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0888 [ 3 ] CAN-2004-0889 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0889 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200410-30.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.
