The remote Red Hat host is missing one or more security updates.
An update for qemu-kvm is now available for Red Hat Enterprise Linux
Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.
Kernel-based Virtual Machine (KVM) is a full virtualization solution
for Linux on a variety of architectures. The qemu-kvm packages provide
the user-space component for running virtual machines that use KVM.
Security Fix(es) :
* A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA
emulator's VNC display driver support; the issue could occur when a
VNC client attempted to update its display after a VGA operation is
performed by a guest. A privileged user/process inside a guest could
use this flaw to crash the QEMU process or, potentially, execute
arbitrary code on the host with privileges of the QEMU process.
