Background ========== Opera is a multi-platform web browser. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-client/opera < 9.24 >= 9.24 Description =========== Michael A. Puls II discovered an unspecified flaw when launching external email or newsgroup clients (CVE-2007-5541). David Bloom discovered that when displaying frames from different websites, the same-origin policy is not correctly enforced (CVE-2007-5540). Impact ====== An attacker could potentially exploit the first vulnerability to execute arbitrary code with the privileges of the user running Opera by enticing a user to visit a specially crafted URL. Note that this vulnerability requires an external e-mail or newsgroup client configured in Opera to be exploitable. The second vulnerability allows an attacker to execute arbitrary script code in a user's browser session in context of other sites or the theft of browser credentials. 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-9.24" References ========== [ 1 ] CVE-2007-5540 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5540 [ 2 ] CVE-2007-5541 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5541 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200710-31.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.
