Scientific Linux Security Update : thunderbird on SL5.x, SL6.x, SL7.x i386/x86_64
Critical Nessus Plugin ID 84895
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionSeveral flaws were found in the processing of malformed web content. A web page containing malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2015-2724, CVE-2015-2725, CVE-2015-2731, CVE-2015-2734, CVE-2015-2735, CVE-2015-2736, CVE-2015-2737, CVE-2015-2738, CVE-2015-2739, CVE-2015-2740)
It was found that Thunderbird skipped key-pinning checks when handling an error that could be overridden by the user (for example an expired certificate error). This flaw allowed a user to override a pinned certificate, which is an action the user should not be able to perform. (CVE-2015-2741)
After installing the update, Thunderbird must be restarted for the changes to take effect.
SolutionUpdate the affected thunderbird and / or thunderbird-debuginfo packages.
