Hi,

I realize you're most likely pretty well aware of that problem already, but
Debian's Xen versions are vulnerable to a PV privilege escalation [1]. The issue
is tracked as CVE-2012-0217 and public as of today.

Therefore I am filing this bug for coordination and traceability. Please update
the packages and consider a security update for Squeeze.
