Multiple vulnerabilities have been discovered in the Xen hypervisor:


Jann Horn discovered a race condition that can cause a stale TLB
entry which might result in privilege escalation, denial of
service or information leak.


Roger Pau Monné discovered a hypervisor stack leak in the x86 I/O
intercept code, resulting in information leaks.


Andrew Cooper discovered that incorrect handling of self-linear
shadow mappings for translated guests might result in denial 
of service or privilege escalation.


Jan Beulich discovered that page type reference counts are
mishandled which may result in denial of service.


Jann Horn discovered that crafted page-table stacking might result
in denial of service, privilege escalation or information leaks.

For Debian 7 "Wheezy", these problems have been fixed in version 4.1.6.lts1-10.

We recommend that you upgrade your xen packages.
