The remote Red Hat host is missing one or more security updates.
An update for qemu-kvm-rhev is now available for RHEV 3.X Hypervisor
and Agents for RHEL-7 and RHEV 4.X RHEV-H and Agents for RHEL-7.
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.
KVM (Kernel-based Virtual Machine) is a full virtualization solution
for Linux on a variety of architectures. The qemu-kvm-rhev packages
provide the user-space component for running virtual machines that use
KVM in environments managed by Red Hat products.
Security Fix(es) :
* An out-of-bounds access issue was found in QEMU's Cirrus CLGD 54xx
VGA Emulator support. The vulnerability could occur while copying VGA
data using bitblt functions (for example,
cirrus_bitblt_rop_fwd_transp_). A privileged user inside a guest could
use this flaw to crash the QEMU process, resulting in denial of
Red Hat would like to thank Jiangxin (PSIRT Huawei Inc.) for reporting
Bug Fix(es) :
* When using post-copy migration with the virtio Random Number
Generator (RNG) device, virtio-rng continued generating data while the
migration was already in post-copy mode. Consequently, the migration
sometimes failed and the error message 'Failed to load
virtio-rng:virtio' was displayed. The source code has been improved
and the problem no longer occurs in the scenario described.
