Scientific Linux Security Update : thunderbird on SL4.x, SL5.x i386/x86_64
High Nessus Plugin ID 60608
SynopsisThe remote Scientific Linux host is missing a security update.
DescriptionSeveral 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 as the user running Thunderbird. (CVE-2009-1392, CVE-2009-1303, CVE-2009-1305, CVE-2009-1833, CVE-2009-1838)
A flaw was found in the way Thunderbird handled error responses returned from proxy servers. If an attacker is able to conduct a man-in-the-middle attack against a Thunderbird instance that is using a proxy server, they may be able to steal sensitive information from the site Thunderbird is displaying. (CVE-2009-1836)
All running instances of Thunderbird must be restarted for the update to take effect.
SolutionUpdate the affected thunderbird package.
