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.
