SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionSeveral 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-2014-1518, CVE-2014-1524, CVE-2014-1529, CVE-2014-1531)
A use-after-free flaw was found in the way Thunderbird resolved hosts in certain circumstances. An attacker could use this flaw to crash Thunderbird or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2014-1532)
An out-of-bounds read flaw was found in the way Thunderbird decoded JPEG images. Loading an email or a web page containing a specially crafted JPEG image could cause Thunderbird to crash. (CVE-2014-1523)
A flaw was found in the way Thunderbird handled browser navigations through history. An attacker could possibly use this flaw to cause the address bar of the browser to display a web page name while loading content from an entirely different web page, which could allow for cross- site scripting (XSS) attacks. (CVE-2014-1530)
After installing the update, Thunderbird must be restarted for the changes to take effect.
SolutionUpdate the affected thunderbird and / or thunderbird-debuginfo packages.
