| Description: | Mozilla Thunderbird is a standalone mail and newsgroup client.Several flaws were found in the processing of malformed web content. A webpage containing malicious content could cause Thunderbird to crash or,potentially, execute arbitrary code with the privileges of the user runningThunderbird. (CVE-2014-1562, CVE-2014-1567)Red Hat would like to thank the Mozilla project for reporting these issues.Upstream acknowledges Jan de Mooij as the original reporter ofCVE-2014-1562, and regenrecht as the original reporter of CVE-2014-1567.Note: All of the above issues cannot be exploited by a specially craftedHTML mail message as JavaScript is disabled by default for mail messages.They could be exploited another way in Thunderbird, for example, whenviewing the full remote content of an RSS feed.For technical details regarding these flaws, refer to the Mozilla securityadvisories for Thunderbird 24.8.0. You can find a link to the Mozillaadvisories in the References section of this erratum.All Thunderbird users should upgrade to this updated package, whichcontains Thunderbird version 24.8.0, which corrects these issues.After installing the update, Thunderbird must be restarted for the changesto take effect. |
