Ubuntu 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.
