Background ========== Dillo is a graphical web browser known for its speed and small footprint. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-client/dillo < 2.1.1 >= 2.1.1 Description =========== Tilei Wang reported an integer overflow in the Png_datainfo_callback() function, possibly leading to a heap-based buffer overflow. Impact ====== A remote attacker could entice a user to open an HTML document containing a specially crafted, large PNG image, 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 Dillo users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose =www-client/dillo-2.1.1 References ========== [ 1 ] CVE-2009-2294 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-2294 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200908-10.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.
