Mandriva Linux Security Advisory 2012-170 - Mozilla Firefox before 16.0.2, Firefox ESR 10.x before 10.0.10, Thunderbird before 16.0.2, Thunderbird ESR 10.x before 10.0.10, and SeaMonkey before 2.13.2 do not prevent use of the valueOf method to shadow the location object, which makes it easier for remote attackers to conduct cross-site scripting attacks via vectors involving a plugin. The nsLocation::CheckURL function in Mozilla Firefox before 16.0.2, Firefox ESR 10.x before 10.0.10, Thunderbird before 16.0.2, Thunderbird ESR 10.x before 10.0.10, and SeaMonkey before 2.13.2 does not properly determine the calling document and principal in its return value, which makes it easier for remote attackers to conduct cross-site scripting attacks via a crafted web site, and makes it easier for remote attackers to execute arbitrary JavaScript code by leveraging certain add-on behavior. Mozilla Firefox before 16.0.2, Firefox ESR 10.x before 10.0.10, Thunderbird before 16.0.2, Thunderbird ESR 10.x before 10.0.10, and SeaMonkey before 2.13.2 allow remote attackers to bypass the Same Origin Policy and read the Location object via a prototype property-injection attack that defeats certain protection mechanisms for this object. The mozilla firefox packages has been upgraded to the latest version which is unaffected by these security flaws.
df5698b16c02425b5dc4629ca3098d7de69fc065a4cbafaa2ba5da169a673deaUbuntu Security Notice 1620-2 - USN-1620-1 fixed vulnerabilities in Firefox. This update provides the corresponding updates for Thunderbird. Please note that Thunderbird is only affected by window.location issues through RSS feeds and extensions that load web content. Mariusz Mlynski and others discovered several flaws in Firefox that allowed a remote attacker to conduct cross-site scripting (XSS) attacks. Antoine Delignat-Lavaud discovered a flaw in the way Firefox handled the Location object. If a user were tricked into opening a specially crafted page, a remote attacker could exploit this to bypass security protections and perform cross-origin reading of the Location object. Various other issues were also addressed.
