Scientific Linux Security Update : thunderbird on SL5.x, SL6.x, SL7.x i386/x86_64

Critical Nessus Plugin ID 84895

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

Several 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)

Note: All of the above issues cannot be exploited by a specially crafted HTML mail message as JavaScript is disabled by default for mail messages. They could be exploited another way in Thunderbird, for example, when viewing the full remote content of an RSS feed.

After installing the update, Thunderbird must be restarted for the changes to take effect.

Solution

Update the affected thunderbird and / or thunderbird-debuginfo packages.
