KVM is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm packages provide the user-space component for running virtual machines using KVM. Security Fix: * Quick Emulator built with the Block driver for iSCSI images support is vulnerable to a heap buffer overflow issue. It could occur while processing iSCSI asynchronous I/O ioctl calls. A user inside guest could use this flaw to crash the Qemu process resulting in DoS or potentially leverage it to execute arbitrary code with privileges of the Qemu process on the host. * Quick emulator 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 for reporting CVE-2016-5403.
