The remote Redhat Enterprise Linux 5 / 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2014:0316 advisory.

    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,     Jri 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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
