Synopsis

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

Description

Multiple security issues have been found in the Xen virtualisation solution, which may result in denial of service or information disclosure.

The oldstable distribution (wheezy) will be updated in a separate DSA.

Solution

Upgrade the xen packages.

For the stable distribution (jessie), these problems have been fixed in version 4.4.1-9+deb8u4.
