Sendmail 'decode' flaw

Vulnerability Assessment Summary
Checks if the remote mail server can be used to overwrite files

Detailed Explanation for this Vulnerability Assessment


The remote SMTP server seems to pipe mail
sent to the 'decode' alias to a program.

There have been in the past a lot of security
problems regarding this, as it would permit
a possible hacker to overwrite arbitrary files
on the remote server.

We suggest you deactivate this alias.


Solution : remove the 'decode' line in /etc/aliases.
