New Thunderbird packages are available for Slackware 11.0 and 12.0 to fix two possible security issues. This package may also be used on many older versions of Slackware (though we're not certain how far back...)

More details about the issues may be found here:

Here are the details from the Slackware 12.0 ChangeLog:
+--------------------------+
patches/packages/mozilla-thunderbird-2.0.0.5-i686-1.tgz:
Upgraded to thunderbird-2.0.0.5. Since Thunderbird shares the browser engine
with Firefox it is susceptible to similar vulnerabilities. This update fixes
the same issues fixed in the recent Firefox patch.
For more information, see:
http://www.mozilla.org/projects/security/known-vulnerabilities.html#thunderbird
(* Security fix *)

HINT: Getting slow download speeds from ftp.slackware.com?
Give slackware.osuosl.org a try. This is another primary FTP site
for Slackware that can be considerably faster than downloading
from ftp.slackware.com.

Thanks to the friendly folks at the OSU Open Source Lab
(http://osuosl.org) for donating additional FTP and rsync hosting
to the Slackware project!

Also see the "Get Slack" section on http://slackware.com for
additional mirror sites near you.
