Red Hat Security Advisory 2017-3474-01 - KVM 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: An assertion-failure flaw was found in the Network Block Device server's initial connection negotiation, where the I/O coroutine 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.

The patch backport for CVE-2017-9375 was incomplete and caused a regression in the USB xHCI controller emulation support. This update fixes the problem. Leo Gaspard discovered that QEMU incorrectly handled VirtFS access control. A guest attacker could use this issue to elevate privileges inside the guest. Li Qiang discovered that QEMU incorrectly handled VMWare PVSCSI emulation. A privileged attacker inside the guest could use this issue to cause QEMU to consume resources or crash, resulting in a denial of service. Various other issues were also addressed.

The qemu-kvm package provides the user-space component for running virtual machines that use KVM. Security Fix: Quick Emulator built with the Network Block Device Server support is vulnerable to a crash via a SIGPIPE signal. The crash can occur if a client aborts a connection due to any failure during negotiation or read operation. A remote user/process could use this flaw to crash the qemu-nbd server resulting in a DoS.
