Background ========== Poppler is a cross-platform PDF rendering library originally based on Xpdf. 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-text/poppler < 0.6.1-r1 >= 0.6.1-r1 2 kde-base/kpdf < 3.5.8-r1 *>= 3.5.7-r3 >= 3.5.8-r1 3 kde-base/kdegraphics < 3.5.8-r1 *>= 3.5.7-r3 >= 3.5.8-r1 4 app-office/kword < 1.6.3-r2 >= 1.6.3-r2 5 app-office/koffice < 1.6.3-r2 >= 1.6.3-r2 ------------------------------------------------------------------- 5 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== Alin Rad Pop (Secunia Research) discovered several vulnerabilities in the "Stream.cc" file of Xpdf: An integer overflow in the DCTStream::reset() method and a boundary error in the CCITTFaxStream::lookChar() method, both leading to heap-based buffer overflows (CVE-2007-5392, CVE-2007-5393). He also discovered a boundary checking error in the DCTStream::readProgressiveDataUnit() method causing memory corruption (CVE-2007-4352). Note: Gentoo's version of Xpdf is patched to use the Poppler library, so the update to Poppler will also fix Xpdf. Impact ====== By enticing a user to view or process a specially crafted PDF file with KWord or KPDF or a Poppler-based program such as Gentoo's viewers Xpdf, ePDFView, and Evince or the CUPS printing system, a remote attacker could cause an overflow, potentially 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 Poppler users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/poppler-0.6.1-r1" All KPDF users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=kde-base/kpdf-3.5.7-r3" All KDE Graphics Libraries users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-3.5.7-r3" All KWord users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-office/kword-1.6.3-r2" All KOffice users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-office/koffice-1.6.3-r2" References ========== [ 1 ] CVE-2007-4352 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4352 [ 2 ] CVE-2007-5392 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5392 [ 3 ] CVE-2007-5393 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5393 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200711-22.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.
