Background ========== Gnash is a GNU flash movie player that supports many SWF features. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-plugins/gnash < 0.8.10-r2 >= 0.8.10-r2 Description =========== Multiple vulnerabilities have been found in Gnash: * The "nsPluginInstance::setupCookies()" function in plugin.cpp creates world-readable cookies with predictable file names (CVE-2011-4328). * The "GnashImage::size()" function in GnashImage.h contains an integer overflow error which could cause a heap-based buffer overflow (CVE-2012-1175). Impact ====== A remote attacker could entice a user to open a specially crafted SWF file, possibly resulting in execution of arbitrary code or a Denial of Service condition. Furthermore, a local attacker may be able to obtain sensitive information. Workaround ========== There is no known workaround at this time. Resolution ========== All Gnash users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-plugins/gnash-0.8.10-r2" References ========== [ 1 ] CVE-2011-4328 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-4328 [ 2 ] CVE-2012-1175 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-1175 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201207-08.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.
