Debian DLA-1230-1 : xen security update

High Nessus Plugin ID 105621

Synopsis

The remote Debian host is missing a security update.

Description

Multiple vulnerabilities have been discovered in the Xen hypervisor, which could result in denial of service, information leaks, privilege escalation or the execution of arbitrary code.

For Debian 7 'Wheezy', these problems have been fixed in version 4.1.6.lts1-11.

We recommend that you upgrade your xen packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
