Background ========== KOffice is an integrated office suite for KDE. KWord is the KOffice word processor. KPDF is a KDE-based PDF viewer included in the kdegraphics package. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-office/koffice < 1.6.3-r1 >= 1.6.3-r1 2 app-office/kword < 1.6.3-r1 >= 1.6.3-r1 3 kde-base/kdegraphics < 3.5.7-r1 >= 3.5.7-r1 4 kde-base/kpdf < 3.5.7-r1 >= 3.5.7-r1 ------------------------------------------------------------------- 4 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== KPDF includes code from xpdf that is vulnerable to an integer overflow in the StreamPredictor::StreamPredictor() function. Impact ====== A remote attacker could entice a user to open a specially crafted PDF file in KWord or KPDF that would exploit the integer overflow to cause a stack-based buffer overflow in the StreamPredictor::getNextLine() function, possibly resulting in the execution of arbitrary code with the privileges of the user running the 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-1.6.3-r1" All KWord users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-office/kword-1.6.3-r1" All KDE Graphics Libraries users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-3.5.7-r1" All KPDF users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=kde-base/kpdf-3.5.7-r1" References ========== [ 1 ] CVE-2007-3387 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3387 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200710-08.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.
