EulerOS Virtualization 2.5.1 : qemu-kvm (EulerOS-SA-2018-1259)

Medium Nessus Plugin ID 117568

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the qemu-kvm packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

- QEMU (aka Quick Emulator), when built with the VGA display emulator support, allows local guest OS privileged users to cause a denial of service (out-of-bounds read and QEMU process crash) via vectors involving display update.(CVE-2017-13672)

- The vga display update in mis-calculated the region for the dirty bitmap snapshot in case split screen mode is used causing a denial of service (assertion failure) in the cpu_physical_memory_snapshot_get_dirty function.(CVE-2017-13673)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected qemu-kvm packages.
