"According to the version of the bind packages installed, the EulerOS
Virtualization for ARM 64 installation on the remote host is affected
by the following vulnerability :

  - In BIND 9.0.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 ->
    9.17.3, also affects 9.9.3-S1 -> 9.11.21-S1 of the BIND
    9 Supported Preview Edition, An attacker on the network
    path for a TSIG-signed request, or operating the server
    receiving the TSIG-signed request, could send a
    truncated response to that request, triggering an
    assertion failure, causing the server to exit.
    Alternately, an off-path attacker would have to
    correctly guess when a TSIG-signed request was sent,
    along with other characteristics of the packet and
    message, and spoof a truncated response to trigger an
    assertion failure, causing the server to
    exit.(CVE-2020-8622)

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.");
