RHSA-2014:0316 - Important: thunderbird security update

Synopsis

Important: thunderbird security update

Type/Severity

Security Advisory Important

Topic

An updated thunderbird package that fixes several security issues is now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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-2014-1493, CVE-2014-1510, CVE-2014-1511, CVE-2014-1512, CVE-2014-1513, CVE-2014-1514)

Several information disclosure flaws were found in the way Thunderbird processed malformed web content. An attacker could use these flaws to gain access to sensitive information such as cross-domain content or protected memory addresses or, potentially, cause Thunderbird to crash. (CVE-2014-1497, CVE-2014-1508, CVE-2014-1505)

A memory corruption flaw was found in the way Thunderbird rendered certain PDF files. An attacker able to trick a user into installing a malicious extension could use this flaw to crash Thunderbird or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2014-1509)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Benoit Jacob, Olli Pettay, Jan Varga, Jan de Mooij, Jesse Ruderman, Dan Gohman, Christoph Diehl, Atte Kettunen, Tyson Smith, Jesse Schwartzentruber, John Thomson, Robert O'Callahan, Mariusz Mlynski, Juri Aedla, George Hotz, and the security research firm VUPEN as the original reporters of these issues.

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.

For technical details regarding these flaws, refer to the Mozilla security advisories for Thunderbird 24.4.0. 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 24.4.0, which corrects these issues. After installing the update, Thunderbird must be restarted for the changes to take effect.
