The remote Red Hat host is missing one or more security updates.
An updated thunderbird package that fixes multiple security issues is
now available for Red Hat Enterprise Linux 5 and 6.
The Red Hat Security Response Team has rated this update as having
critical security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.
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,
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)
