"According to the versions of the qemu-kvm packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :
- Quick emulator (QEMU) built with the Cirrus CLGD 54xx
VGA emulator support is vulnerable to an out-of-bounds
access issue. It could occur while copying VGA data via
bitblt copy in backward mode. A privileged user inside
a guest could use this flaw to crash the QEMU process
resulting in DoS or potentially execute arbitrary code
on the host with privileges of QEMU process on the
host. (CVE-2017-2615)
- Quick emulator (QEMU) built with the Cirrus CLGD 54xx
VGA Emulator support is vulnerable to an out-of-bounds
access issue. The issue could occur while copying VGA
data in cirrus_bitblt_cputovideo. A privileged user
inside guest could use this flaw to crash the QEMU
process OR potentially execute arbitrary code on host
with privileges of the QEMU process. (CVE-2017-2620)
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.");
