The remote Red Hat host is missing one or more security updates.
An update for qemu-kvm-rhev is now available for RHEV-H and Agents for
Red Hat Product Security has rated this update as having a security
impact of Moderate. 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 AMD64 and Intel 64 systems. The qemu-kvm-rhev package
provides the user-space component for running virtual machines using
KVM in environments managed by Red Hat Enterprise Virtualization
Security Fix(es) :
* Quick emulator(Qemu) built with the virtio framework is vulnerable
to an unbounded memory allocation issue. It was found that a malicious
guest user could submit more requests than the virtqueue size permits.
Processing a request allocates a VirtQueueElement and therefore causes
unbounded memory allocation on the host controlled by the guest.
Red Hat would like to thank hongzhenhao (Marvel Team) for reporting
