CentOS Errata and Security Advisory CESA-2017:1681
Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm package provides the user-space component for running virtual machines that use KVM.
Security Fix(es):
- Quick Emulator (QEMU) built with Network Block Device (NBD) Server support was vulnerable to a null-pointer dereference issue. The flaw could occur when releasing a client, which was not initialized due to failed negotiation. A remote user or process could exploit this flaw to crash the qemu-nbd server (denial of service). (CVE-2017-9524)
