CentOS Errata and Security Advisory CESA-2014:0918
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-2014-1547, CVE-2014-1555, CVE-2014-1556, CVE-2014-1557)
Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Christian Holler, David Keeler, Byron Campen, Jethro Beekman, Patrick Cozzi, and Mozilla community member John as the original reporters of these issues.
For technical details regarding these flaws, refer to the Mozilla security advisories for Thunderbird 24.7.0. 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 24.7.0, which corrects these issues. After installing the update, Thunderbird must be restarted for the changes to take effect.
