For Debian 7 "Wheezy", these problems have been fixed in version 4.1.6.lts1-12. We recommend that you upgrade your xen packages. Please note that CVE-2017-15590 (XSA-237) will *not* be fixed in wheezy as the patches are too intrusive to backport. The vulnerability can be mitigated by not passing through physical devices to untrusted guests.
