high Nessus Plugin ID 18942

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

Nobuhiro IMAI reports :

the default value modification on Module#public_instance_methods (from false to true) breaks s.add_handler(XMLRPC::iPIMethods('sample'), MyHandler.new) style security protection.

This problem could allow a remote attacker to execute arbitrary commands on XMLRPC server of libruby.

Solution

Update the affected packages.
