Background ========== Opera is a multi-platform web browser. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-client/opera < 8.54 >= 8.54 Description =========== SEC Consult has discovered a buffer overflow in the code processing style sheet attributes. It is caused by an integer signedness error in a length check followed by a call to a string function. It seems to be hard to exploit this buffer overflow to execute arbitrary code because of the very large amount memory that has to be copied. Impact ====== A remote attacker can entice a user to visit a web page containing a specially crafted style sheet attribute that will crash the user's browser and maybe lead to the execution of arbitrary code. Workaround ========== There is no known workaround at this time. Resolution ========== All Opera users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-client/opera-8.54" References ========== [ 1 ] CVE-2006-1834 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-1834 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200606-01.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.
