medium Nessus Plugin ID 84717

Language:

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

The Xen Project reports :

The xl command line utility mishandles long configuration values when passed as command line arguments, with a buffer overrun.

A semi-trusted guest administrator or controller, who is intended to be able to partially control the configuration settings for a domain, can escalate their privileges to that of the whole host.

Solution

Update the affected package.
