Background ========== Opera is a multi-platform web browser. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-client/opera < 9.23 >= 9.23 Description =========== An error known as "a virtual function call on an invalid pointer" has been discovered in the JavaScript engine (CVE-2007-4367). Furthermore, iDefense Labs reported that an already-freed pointer may be still used under unspecified circumstances in the BitTorrent support (CVE-2007-3929). At last, minor other errors have been discovered, relative to memory read protection (Opera Advisory 861) and URI displays (CVE-2007-3142, CVE-2007-3819). Impact ====== A remote attacker could trigger the BitTorrent vulnerability by enticing a user into starting a malicious BitTorrent download, and execute arbitrary code through unspecified vectors. Additionally, a specially crafted JavaScript may trigger the "virtual function" vulnerability. The JavaScript engine can also access previously freed but uncleaned memory. Finally, a user can be fooled with a too long HTTP server name that does not fit the dialog box, or a URI containing whitespaces. Workaround ========== There is no known workaround at this time for all these vulnerabilities. Resolution ========== All Opera users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-client/opera-9.23" References ========== [ 1 ] CVE-2007-3142 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3142 [ 2 ] CVE-2007-3819 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3819 [ 3 ] CVE-2007-3929 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3929 [ 4 ] CVE-2007-4367 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4367 [ 5 ] Opera Advisory 861 http://www.opera.com/support/search/view/861/ Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200708-17.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.
