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.

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

For the unstable distribution (sid), these problems will be fixed soon.

We recommend that you upgrade your xen packages.
