DESCRIPTION:
Some vulnerabilities have been reported in the Mail gem for Ruby,
which can be exploited by malicious people to manipulate certain data
and compromise a vulnerable system.

1) Input passed via the "to" parameter within the file delivery
method is not properly verified before being used and can be
exploited to modify arbitrary files via directory traversal attacks.

2) Certain input passed to the sendmail and exim delivery methods is
not properly sanitised before being used as a command line argument
and can be exploited to inject arbitrary shell commands.

Successful exploitation of this vulnerability may allow execution of
arbitrary code, but requires an application using the gem to accept
untrusted input.

The vulnerabilities are reported in versions prior to 2.4.4.

SOLUTION:
Update to version 2.4.4.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
