"According to the version of the openssh packages installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerability :
- OpenSSH 7.7 through 7.9 and 8.x before 8.1, when
compiled with an experimental key type, has a
pre-authentication integer overflow if a client or
server is configured to use a crafted XMSS key. This
leads to memory corruption and remote code execution
because of an error in the XMSS key parsing algorithm.
NOTE: the XMSS implementation is considered
experimental in all released OpenSSH versions, and
there is no supported way to enable it when building
portable OpenSSH.(CVE-2019-16905)
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.");
