| Title: | RHSA-2016:2585: qemu-kvm security, bug fix, and enhancement update (Moderate) |
| Description: | 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.
