Vulnerability identifier: #VU95740

CSH Severity: Low

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The Xen hypervisor block backend driver for Linux kernel 2.6.18, when running on a 64-bit host with a 32-bit paravirtualized guest, allows local privileged users in the guest OS to cause a denial of service (host OS crash) via a request that specifies a large number of blocks.
