GCVE-110-MAGEIA-2014-36

Updated firefox and thunderbird packages fix security vulnerabilities: Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox or Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running it (CVE-2014-1477, CVE-2014-1482, CVE-2014-1486). A flaw was found in the way Firefox and Thunderbird handled error messages related to web workers. An attacker could use this flaw to bypass the same-origin policy, which could lead to cross-site scripting (XSS) attacks, or could potentially be used to gather authentication tokens and other data from third-party websites (CVE-2014-1487). A flaw was found in the implementation of System Only Wrappers (SOW). An attacker could use this flaw to crash Firefox or Thunderbird. When combined with other vulnerabilities, this flaw could have additional security implications (CVE-2014-1479). It was found that the Firefox and Thunderbird JavaScript engine incorrectly handled window objects. A remote attacker could use this flaw to bypass certain security checks and possibly execute arbitrary code (CVE-2014-1481).
