The remote SUSE Linux SLES11 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2020:14511-1 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

- The Raccoon attack exploits a flaw in the TLS specification which can lead to an attacker being able to
compute the pre-master secret in connections which have used a Diffie-Hellman (DH) based ciphersuite. In
such a case this would result in the attacker being able to eavesdrop on all encrypted communications sent
over that TLS connection. The attack can only be exploited if an implementation re-uses a DH secret across
multiple TLS connections. Note that this issue only impacts DH ciphersuites and not ECDH ciphersuites.
This issue affects OpenSSL 1.0.2 which is out of support and no longer receiving public updates. OpenSSL
1.1.1 is not vulnerable to this issue. Fixed in OpenSSL 1.0.2w (Affected 1.0.2-1.0.2v). (CVE-2020-1968)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
