New! Plugin Severity Now Using CVSS v3

Synopsis

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

Description

The Xen Project reports :

A heap overflow flaw was found in the way QEMU's IDE subsystem handled I/O buffer access while processing certain ATAPI commands.

A privileged guest user in a guest with CDROM drive enabled could potentially use this flaw to execute arbitrary code on the host with the privileges of the host's QEMU process corresponding to the guest.

Solution

Update the affected packages.
