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

This script is Copyright (C) 2015 Tenable Network Security, Inc.


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.
