Synopsis
Moderate: qemu-kvm security, bug fix, and enhancement update
Type/Severity
Security Advisory: Moderate
Topic
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.
Description
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):
- An out-of-bounds memory access issue was found in Quick Emulator (QEMU) in the VNC display driver. This flaw could occur while refreshing the VNC display surface area in the 'vnc_refresh_server_surface'. A user inside a guest could use this flaw to crash the QEMU process. (CVE-2017-2633)
- An integer overflow flaw was found in Quick Emulator (QEMU) in the CCID Card device support. The flaw could occur while passing messages via command/response packets to and from the host. A privileged user inside a guest could use this flaw to crash the QEMU process. (CVE-2017-5898)
- An information exposure flaw was found in Quick Emulator (QEMU) in Task Priority Register (TPR) optimizations for 32-bit Windows guests. The flaw could occur while accessing TPR. A privileged user inside a guest could use this issue to read portions of the host memory. (CVE-2016-4020)
Red Hat would like to thank Li Qiang (360.cn Inc.) for reporting CVE-2017-5898 and Donghai Zdh (Alibaba Inc.) for reporting CVE-2016-4020.
