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

high Nessus Plugin ID 75887

Language:

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).

Solution

Update the affected kvm packages.
