RHSA-2014:1924 -- thunderbird security update (Important)

oval:org.mitre.oval:def:28459

Mozilla Thunderbird is a standalone mail and newsgroup client. 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: <A HREF="https://access.redhat.com/articles/1284233">https://access.redhat.com/articles/1284233</A> Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Gary Kwong Randell Jesup Nils Ohlmeier Jesse Ruderman Max Jonas Werner Joe Vennix Berend-Jan Wever Abhishek Arya and Boris Zbarsky as the original reporters of these issues. For technical details regarding these flaws refer to the Mozilla security advisories for Thunderbird 31.3.0. You can find a link to the Mozilla advisories in the References section of this erratum. All Thunderbird users should upgrade to this updated package which contains Thunderbird version 31.3.0 which corrects these issues. After installing the update Thunderbird must be restarted for the changes to take effect.
