openSUSE Security Update : kvm (openSUSE-SU-2011:0510-1)

This script is Copyright (C) 2014 Tenable Network Security, Inc.


Synopsis :

The remote openSUSE host is missing a security update.

Description :

By causing a hot-unplug of the pci-isa bridge from within guests the
qemu process could access already freed memory. A privileged user
inside the guest could exploit that to crash the guest instance or
potentially execute arbitrary code on the host (CVE-2011-1751).

The virtio-blk driver did not properly validate read and write
request. A privileged user inside the guest could exploit that to
cause a heap corruption and crash the guest instance or potentially
execute arbitrary code on the host (CVE-2011-1750).
