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 assertion-failure flaw was found in the Network Block Device (NBD) server’s initial connection negotiation, where the I/O co-routine was undefined. This could crash the qemu-nbd server if a client sent unexpected data during connection negotiation. A remote user or process could use this flaw to crash the qemu-nbd server resulting in denial of service. (CVE-2017-7539)
