Background ========== KOffice is an integrated office suite for KDE. KWord is the KOffice word processor. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-office/koffice < 1.4.1-r1 >= 1.4.1-r1 2 app-office/kword < 1.4.1-r1 >= 1.4.1-r1 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== Chris Evans discovered that the KWord RTF importer was vulnerable to a heap-based buffer overflow. Impact ====== An attacker could entice a user to open a specially-crafted RTF 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 KOffice users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-office/koffice-1.4.1-r1" All KWord users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-office/kword-1.4.1-r1" References ========== [ 1 ] CAN-2005-2971 http://cve.mitre.org/cgi-bin/cvename.cgi?name=2005-2971 [ 2 ] KDE Security Advisory: KWord RTF import buffer overflow http://www.kde.org/info/security/advisory-20051011-1.txt Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200510-12.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.
