"This update fixes various Xen 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.

  - 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). (CVE-2007-5907)

Also the following bugs were fixed: 279062: Timer ISR/1: Time went
backwards 340379: Xen-3.04_13138-0.52 not working with FV File-Backed
VMs"
