From Help Net Security: “There are many patches that need to be applied to properly close these holes, so they
are not included here. If you will not be upgrading your system to 2.14 and instead wish
to apply these patches to your existing system, please consult the bug reports on
bugzilla.mozilla.org for the bug numbers listed below, where you can obtain the patches
attached to those bugs.”
