CVE-2011-1166

A 64-bit guest can get one of its vCPU'ss into non-kernel
mode without first providing a valid non-kernel pagetable,
thereby locking up the host system.

CVE-2011-1583, CVE-2011-3262

Local users can cause a denial of service and possibly execute
arbitrary code via a crafted paravirtualised guest kernel image.

CVE-2011-1898

When using PCI passthrough on Intel VT-d chipsets that do not
have interrupt remapping, guest OS can users to gain host OS
privileges by writing to the interrupt injection registers.

The oldstable distribution (lenny) contains a different version of Xen
not affected by these problems.

For the stable distribution (squeeze), this problem has been fixed in
version 4.0.1-4.

For the testing (wheezy) and unstable distribution (sid), this problem
has been fixed in version 4.1.1-1.");
