The remote Red Hat host is missing one or more security updates.
An updated thunderbird package that fixes several 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
important 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-2014-1477, CVE-2014-1482, CVE-2014-1486)
A flaw was found in the way Thunderbird handled error messages related
to web workers. An attacker could use this flaw to bypass the
same-origin policy, which could lead to cross-site scripting (XSS)
attacks, or could potentially be used to gather authentication tokens
and other data from third-party websites. (CVE-2014-1487)
A flaw was found in the implementation of System Only Wrappers (SOW).
An attacker could use this flaw to crash Thunderbird. When combined
with other vulnerabilities, this flaw could have additional security
handled window objects. A remote attacker could use this flaw to
bypass certain security checks and possibly execute arbitrary code.
Red Hat would like to thank the Mozilla project for reporting these
issues. Upstream acknowledges Christian Holler, Terrence Cole, Jesse
Ruderman, Gary Kwong, Eric Rescorla, Jonathan Kew, Dan Gohman, Ryan
VanderMeulen, Sotaro Ikeda, Cody Crews, Fredrik 'Flonka' Lonnqvist,
Arthur Gerkis, Masato Kinugawa, and Boris Zbarsky as the original
reporters of these issues.
Note: All of the above issues cannot be exploited by a specially
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 24.3.0. 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 24.3.0, which corrects these issues.
After installing the update, Thunderbird must be restarted for the
changes to take effect.
