Synopsis: Important: thunderbird security update Advisory ID: SLSA-2014:1924-1 Issue Date: 2014-12-02 CVE Numbers: CVE-2014-1587 CVE-2014-1590 CVE-2014-1592 CVE-2014-1593 CVE-2014-1594 -- Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2014-1587, CVE-2014-1590, CVE-2014-1592, CVE-2014-1593) A flaw was found in the Alarm API, which could allow applications to schedule actions to be run in the future. A malicious web application could use this flaw to bypass the same-origin policy. (CVE-2014-1594) 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. This update disables SSL 3.0 support by default in Thunderbird. Details on how to re-enable SSL 3.0 support are available at: After installing the update, Thunderbird must be restarted for the changes to take effect. -- SL6 x86_64 thunderbird-31.3.0-1.el6_6.x86_64.rpm thunderbird-debuginfo-31.3.0-1.el6_6.x86_64.rpm i386 thunderbird-31.3.0-1.el6_6.i686.rpm thunderbird-debuginfo-31.3.0-1.el6_6.i686.rpm - Scientific Linux Development Team
