Security Update for Thunderbird

Mozilla has released a new version, 17.0.4., of its Thunderbird E-mail client, for Linux, Windows, and Mac OS X.   This is primarily a security-fix release; the new version corrects a critical vulnerability in the HTML editor component.  The Release Notes don’t say much more.

Because of the security fixes incorporated in this release, I recommend that you update your systems as soon as you conveniently can.  You can use the update mechanism built into the software (Help / About Thunderbird / Check for Updates), or you can get a complete installation package, in a variety of languages, from the Thunderbird download page.

Thunderbird Updated to 16.0.1

The Mozilla organization today released a new version, 16.0.1, of its Thunderbird E-mail client for Linux, Mac OS X, and Windows.  This corresponds to the release of Firefox 16.0.1, and addresses the same security vulnerability that was accidentally introduced in the 16.0 versions of the software.  (Firefox and Thunderbird share a substantial amount of code.)   The Release Notes have also been updated to reflect the change./

You can obtain the new version via the built-in update mechanism (Help / About Thunderbird / Check for Updates), or you can get a complete installation package from the Thunderbird download page.
