Synopsis: Important: thunderbird security update Advisory ID: SLSA-2014:0133-1 Issue Date: 2014-02-04 CVE Numbers: CVE-2014-1477 CVE-2014-1479 CVE-2014-1482 CVE-2014-1486 CVE-2014-1487 CVE-2014-1481 -- Several flaws were found in the processing of malformed content. Malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2014-1477, CVE-2014-1482, CVE-2014-1486) A flaw was found in the way 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 Thunderbird. When combined with other vulnerabilities, this flaw could have additional security implications. (CVE-2014-1479) It was found that the 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) Note: All of the above issues cannot be exploited by a specially crafted HTML mail message as JavaScript is disabled by default for mail messages. They could be exploited another way in Thunderbird, for example, when viewing the full remote content of an RSS feed. After installing the update, Thunderbird must be restarted for the changes to take effect. -- SL5 x86_64 thunderbird-24.3.0-2.el5_10.x86_64.rpm thunderbird-debuginfo-24.3.0-2.el5_10.x86_64.rpm i386 thunderbird-24.3.0-2.el5_10.i386.rpm thunderbird-debuginfo-24.3.0-2.el5_10.i386.rpm SL6 x86_64 thunderbird-24.3.0-2.el6_5.x86_64.rpm thunderbird-debuginfo-24.3.0-2.el6_5.x86_64.rpm i386 thunderbird-24.3.0-2.el6_5.i686.rpm thunderbird-debuginfo-24.3.0-2.el6_5.i686.rpm - Scientific Linux Development Team
