"According to the versions of the openssl110f packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - During key agreement in a TLS handshake using a DH(E)
    based ciphersuite a malicious server can send a very
    large prime value to the client. This will cause the
    client to spend an unreasonably long period of time
    generating a key for this prime resulting in a hang
    until the client has finished. This could be exploited
    in a Denial Of Service attack.(CVE-2017-0732)

  - OpenSSL RSA key generation was found to be vulnerable
    to cache side-channel attacks. An attacker with
    sufficient access to mount cache timing attacks during
    the RSA key generation process could recover parts of
    the private key.(CVE-2018-0737)

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.");
