Title:RHSA-2015:1455: thunderbird security update (Important)
Description: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-2015-2724, CVE-2015-2725, CVE-2015-2731, CVE-2015-2734, CVE-2015-2735, CVE-2015-2736, CVE-2015-2737, CVE-2015-2738, CVE-2015-2739, CVE-2015-2740)

  • It was found that Thunderbird skipped key-pinning checks when handling an error that could be overridden by the user (for example an expired certificate error). This flaw allowed a user to override a pinned certificate, which is an action the user should not be able to perform. (CVE-2015-2741)

    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.

    Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Bob Clary, Christian Holler, Bobby Holley, Andrew McCreight, Herre, Ronald Crane, and David Keeler as the original reporters of these issues.

    For technical details regarding these flaws, refer to the Mozilla security advisories for Thunderbird 31.8. 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 31.8, which corrects these issues. After installing the update, Thunderbird must be restarted for the changes to take effect.
