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

  - A cached side channel attack during handshakes using
    RSA encryption could allow for the decryption of
    encrypted content. This is a variant of the Adaptive
    Chosen Ciphertext attack (AKA Bleichenbacher attack)
    and affects all NSS versions prior to NSS
    3.41.(CVE-2018-12404)

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.");
