DESCRIPTION:
A vulnerability has been reported in the Mail gem for Ruby, which can
be exploited by malicious people to compromise a vulnerable system.

Input passed via an email from address is not properly sanitised in
the "deliver()" function
(lib/mail/network/delivery_methods/sendmail.rb) before being used as
a command line argument. This can be exploited to inject arbitrary
shell commands.

Successful exploitation requires the gem to use sendmail for mail
delivery.

The vulnerability is reported versions prior to 2.2.15.

SOLUTION:
Update to version 2.2.15.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Andy Lindeman and Steven Lorek.
