    descriptionThis 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. 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). 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
