[Scott C. <z5...@z5...>]

  Update Information

A security update is available for thunderbird for the following
versions of Cucumber Linux:

  * 1.0
  * 1.1 Beta

Here are the details from the Cucumber 1.0 changelog:

+----------------+
Fri Dec 22 20:53:10 EST 2017
xapps-general/thunderbird upgraded to fix the "Mailsploit" vulnerability, a
	security vulnerability which could allow for a remote attacker to
	arbitrarily spoof the "From" address in an email. These spoofed emails
	get past most spam filters and show up in Thunderbird as being from any
	email address of the attacker's choosing (such as po...@wh...).
	For more information see:

* SECURITY FIX *
+----------------+

As a side note, this serves as an excellent example of why we
cryptographically sign all of our security related emails. :)
