DistCC Detection

Detect the presence of DistCC

Detailed Explanation for this Vulnerability Assessment

Summary :

A distributed compiler is listening on the remote port.

Description :

The remote host is running distcc, a distributed GCC compiler.
distcc permits a user to use the resources several hosts to
compile his programs more quickly.

As distcc permits anyone to execute arbitrary commands on the
remote host, it should be configured to only accept connections
from a restricted set of IP addresses, otherwise a possible hacker
can use it to obtain an interactive shell on the remote host,
with the rights of the distcc daemon (usually 'distccd')

Solution :

Filter incoming traffic to this port, or use the '-a' option
switch to restrict the set of IP addresses distcc will accept.
