Background ========== Opera is a multi-platform web browser. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-client/opera < 9.10 >= 9.10 Description =========== Christoph Deal discovered that JPEG files with a specially crafted DHT marker can be exploited to cause a heap overflow. Furthermore, an anonymous person discovered that Opera does not correctly handle objects passed to the "createSVGTransformFromMatrix()" function. Impact ====== An attacker could potentially exploit the vulnerabilities to execute arbitrary code with the privileges of the user running Opera by enticing a victim to open a specially crafted JPEG file or a website containing malicious JavaScript code. Workaround ========== The vendor recommends disabling JavaScript to avoid the "createSVGTransformFromMatrix" vulnerability. There is no known workaround for the other vulnerability. Resolution ========== All Opera users should update to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-client/opera-9.10" References ========== [ 1 ] Opera Advisory (createSVGTransformFromMatrix) http://www.opera.com/support/search/supsearch.dml?index=851 [ 2 ] Opera Advisory (JPEG) http://www.opera.com/support/search/supsearch.dml?index=852 [ 3 ] CVE-2007-0126 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0126 [ 4 ] CVE-2007-0127 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0127 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200701-08.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.
