"According to the version of the libvirt packages installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerability :
- A double free memory issue was found to occur in the
libvirt API, in versions before 6.8.0, responsible for
requesting information about network interfaces of a
running QEMU domain. This flaw affects the polkit
access control driver. Specifically, clients connecting
to the read-write socket with limited ACL permissions
could use this flaw to crash the libvirt daemon,
resulting in a denial of service, or potentially
escalate their privileges on the system. The highest
threat from this vulnerability is to data
confidentiality and integrity as well as system
availability.(CVE-2020-25637)
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.");
