The remote Redhat Enterprise Linux 5 / 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2012:0715 advisory.

    Mozilla Thunderbird is a standalone mail and newsgroup client.

    Several flaws were found in the processing of malformed content. Malicious     content could cause Thunderbird to crash or, potentially, execute arbitrary     code with the privileges of the user running Thunderbird. (CVE-2011-3101,     CVE-2012-1937, CVE-2012-1938, CVE-2012-1939, CVE-2012-1940, CVE-2012-1941,     CVE-2012-1946, CVE-2012-1947)

    Note: CVE-2011-3101 only affected users of certain NVIDIA display drivers     with graphics cards that have hardware acceleration enabled.

    It was found that the Content Security Policy (CSP) implementation in     Thunderbird no longer blocked Thunderbird inline event handlers. Malicious     content could possibly bypass intended restrictions if that content relied     on CSP to protect against flaws such as cross-site scripting (XSS).
    (CVE-2012-1944)

    If a web server hosted content that is stored on a Microsoft Windows share,     or a Samba share, loading such content with Thunderbird could result in     Windows shortcut files (.lnk) in the same share also being loaded. An     attacker could use this flaw to view the contents of local files and     directories on the victim's system. This issue also affected users opening     content from Microsoft Windows shares, or Samba shares, that are mounted     on their systems. (CVE-2012-1945)

    Red Hat would like to thank the Mozilla project for reporting these issues.
    Upstream acknowledges Ken Russell of Google as the original reporter of     CVE-2011-3101; Igor Bukanov, Olli Pettay, Boris Zbarsky, and Jesse Ruderman     as the original reporters of CVE-2012-1937; Jesse Ruderman, Igor Bukanov,     Bill McCloskey, Christian Holler, Andrew McCreight, and Brian Bondy as the     original reporters of CVE-2012-1938; Christian Holler as the original     reporter of CVE-2012-1939; security researcher Abhishek Arya of Google as     the original reporter of CVE-2012-1940, CVE-2012-1941, and CVE-2012-1947;
    security researcher Arthur Gerkis as the original reporter of     CVE-2012-1946; security researcher Adam Barth as the original reporter of     CVE-2012-1944; and security researcher Paul Stone as the original reporter     of CVE-2012-1945.

    Note: None of the issues in this advisory can 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.

    All Thunderbird users should upgrade to this updated package, which     contains Thunderbird version 10.0.5 ESR, 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.
