An update for qemu-kvm is now available for Red Hat Enterprise Linux 7.

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.

Kernel-based Virtual Machine (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(es) :

* An integer overflow flaw and an out-of-bounds read flaw were found in the way QEMU's VGA emulator set certain VGA registers while in VBE mode. A privileged guest user could use this flaw to crash the QEMU process instance. (CVE-2016-3712)

* An infinite loop flaw was found in the way QEMU's e1000 NIC emulation implementation processed data using transmit or receive descriptors under certain conditions. A privileged user inside a guest could use this flaw to crash the QEMU instance. (CVE-2016-1981)

Red Hat would like to thank Zuozhi Fzz (Alibaba Inc.) for reporting CVE-2016-3712.
