The remote Redhat Enterprise Linux 5 / 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2012:0516 advisory.

    Mozilla Thunderbird is a standalone mail and newsgroup client.

    A flaw was found in Sanitiser for OpenType (OTS), used by Thunderbird to     help prevent potential exploits in malformed OpenType fonts. Malicious     content could cause Thunderbird to crash or, under certain conditions,     possibly execute arbitrary code with the privileges of the user running     Thunderbird. (CVE-2011-3062)

    Malicious content could cause Thunderbird to crash or, potentially, execute     arbitrary code with the privileges of the user running Thunderbird.
    (CVE-2012-0467, CVE-2012-0468, CVE-2012-0469)

    Content containing a malicious Scalable Vector Graphics (SVG) image file     could cause Thunderbird to crash or, potentially, execute arbitrary code     with the privileges of the user running Thunderbird. (CVE-2012-0470)

    A flaw was found in the way Thunderbird used its embedded Cairo library to     render certain fonts. Malicious content could cause Thunderbird to crash     or, under certain conditions, possibly execute arbitrary code with the     privileges of the user running Thunderbird. (CVE-2012-0472)

    A flaw was found in the way Thunderbird rendered certain images using     WebGL. Malicious content could cause Thunderbird to crash or, under certain     conditions, possibly execute arbitrary code with the privileges of the user     running Thunderbird. (CVE-2012-0478)

    A cross-site scripting (XSS) flaw was found in the way Thunderbird handled     certain multibyte character sets. Malicious content could cause Thunderbird     to run JavaScript code with the permissions of different content.
    (CVE-2012-0471)

    A flaw was found in the way Thunderbird rendered certain graphics using     WebGL. Malicious content could cause Thunderbird to crash. (CVE-2012-0473)

    A flaw in the built-in feed reader in Thunderbird allowed the Website field     to display the address of different content than the content the user was     visiting. An attacker could use this flaw to conceal a malicious URL,     possibly tricking a user into believing they are viewing a trusted site, or     allowing scripts to be loaded from the attacker's site, possibly leading to     cross-site scripting (XSS) attacks. (CVE-2012-0474)

    A flaw was found in the way Thunderbird decoded the ISO-2022-KR and     ISO-2022-CN character sets. Malicious content could cause Thunderbird     to run JavaScript code with the permissions of different content.
    (CVE-2012-0477)

    A flaw was found in the way the built-in feed reader in Thunderbird handled     RSS and Atom feeds. Invalid RSS or Atom content loaded over HTTPS caused     Thunderbird to display the address of said content, but not the content.
    The previous content continued to be displayed. An attacker could use this     flaw to perform phishing attacks, or trick users into thinking they are     visiting the site reported by the Website field, when the page is actually     content controlled by an attacker. (CVE-2012-0479)

    Red Hat would like to thank the Mozilla project for reporting these issues.
    Upstream acknowledges Mateusz Jurczyk of the Google Security Team as the     original reporter of CVE-2011-3062; Aki Helin from OUSPG as the original     reporter of CVE-2012-0469; Atte Kettunen from OUSPG as the original     reporter of CVE-2012-0470; wushi of team509 via iDefense as the original     reporter of CVE-2012-0472; Ms2ger as the original reporter of     CVE-2012-0478; Anne van Kesteren of Opera Software as the original reporter     of CVE-2012-0471; Matias Juntunen as the original reporter of     CVE-2012-0473; Jordi Chancel and Eddy Bordi, and Chris McGowen as the     original reporters of CVE-2012-0474; Masato Kinugawa as the original     reporter of CVE-2012-0477; and Jeroen van der Gun as the original reporter     of CVE-2012-0479.

    Note: All issues except CVE-2012-0470, CVE-2012-0472, and CVE-2011-3062     cannot be exploited by a specially-crafted HTML mail message as JavaScript     is disabled by default for mail messages. It could be exploited another way     in Thunderbird, for example, when viewing the full remote content of an     RSS feed.

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.
