qemu-kvm-1.5.3-141.el7.4

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), compiled with the PC System Emulator with multiboot feature support, is vulnerable to an OOB r/w memory access issue. The issue could occur due to an integer overflow while loading a kernel image during a guest boot. A user or process could use this flaw to potentially achieve arbitrary code execution on a host. (CVE-2017-14167)

* Quick emulator (QEMU), compiled with the Cirrus CLGD 54xx VGA Emulator support, is vulnerable to an OOB write access issue. The issue could occur while writing to VGA memory via mode4and5 write functions. A privileged user inside guest could use this flaw to crash the QEMU process resulting in Denial of Serivce (DoS). (CVE-2017-15289)

CVE-2017-14167
Integer overflow in the load_multiboot function in hw/i386/multiboot.c
in QEMU (aka Quick Emulator) allows local guest OS users to execute
arbitrary code on the host via crafted multiboot header address
values, which trigger an out-of-bounds write.
CVE-2017-15289
The mode4and5 write functions in hw/display/cirrus_vga.c in Qemu allow
local OS guest privileged users to cause a denial of service
(out-of-bounds write access and Qemu process crash) via vectors
related to dst calculation.
