SuSE 11.3 Security Update : kvm (SAT Patch Number 9739)

High Nessus Plugin ID 78105

Synopsis

The remote SuSE 11 host is missing a security update.

Description

kvm has been updated to fix issues in the embedded qemu :

- An integer overflow flaw was found in the QEMU block driver for QCOW version 1 disk images. A user able to alter the QEMU disk image files loaded by a guest could have used this flaw to corrupt QEMU process memory on the host, which could potentially have resulted in arbitrary code execution on the host with the privileges of the QEMU process. (CVE-2014-0223)

- A user able to alter the savevm data (either on the disk or over the wire during migration) could have used this flaw to to corrupt QEMU process memory on the (destination) host, which could have potentially resulted in arbitrary code execution on the host with the privileges of the QEMU process. (CVE-2014-3461)
