Synopsis :

The remote Fedora host is missing a security update.

Description :

Overflows in kernel decompression can allow root on xen PV guest to
gain privileged access to base domain, or access to xen configuration
info. Lack of error checking could allow DoS attack from guest.
[CVE-2011-1583] Don't require /usr/bin/qemu-nbd as it isn't used at
present.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
