SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionSeveral 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-2013-0775, CVE-2013-0780, CVE-2013-0782, CVE-2013-0783)
It was found that, after canceling a proxy server's authentication prompt, the address bar continued to show the requested site's address. An attacker could use this flaw to conduct phishing attacks by tricking a user into believing they are viewing trusted content.
Important: This erratum upgrades Thunderbird to version 17.0.3 ESR.
Thunderbird 17 is not completely backwards-compatible with all Mozilla add-ons and Thunderbird plug-ins that worked with Thunderbird 10.0.
Thunderbird 17 checks compatibility on first-launch, and, depending on the individual configuration and the installed add-ons and plug-ins, may disable said Add-ons and plug-ins, or attempt to check for updates and upgrade them. Add-ons and plug-ins may have to be manually updated.
After installing the update, Thunderbird must be restarted for the changes to take effect.
SolutionUpdate the affected thunderbird and / or thunderbird-debuginfo packages.
