High Nessus Plugin ID 50038
SynopsisThe remote Red Hat host is missing a security update.
DescriptionAn updated thunderbird package that fixes several security issues is now available for Red Hat Enterprise Linux 4 and 5.
The Red Hat Security Response Team has rated this update as having moderate 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 HTML mail content. An HTML mail message containing malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2010-3176, CVE-2010-3180)
A flaw was found in the script that launches Thunderbird. The LD_LIBRARY_PATH variable was appending a '.' character, which could allow a local attacker to execute arbitrary code with the privileges of a different user running Thunderbird, if that user ran Thunderbird from within an attacker-controlled directory. (CVE-2010-3182)
All Thunderbird users should upgrade to this updated package, which resolves these issues. All running instances of Thunderbird must be restarted for the update to take effect.
SolutionUpdate the affected thunderbird package.
