This update fixes Xen security issues.

Two security problems were fixed: CVE-2007-5906: Xen allowed virtual guest system users to cause a denial of service (hypervisor crash) by using a debug register (DR7) to set certain breakpoints.

CVE-2007-5907: Xen 3.1.1 does not prevent modification of the CR4 TSC from applications, which allows pv guests to cause a denial of service (crash).
