Vulnerability Details
CVEID: CVE-2018-15473
DESCRIPTION: OpenSSH could allow a remote attacker to obtain sensitive
information, caused by different responses to valid and invalid authentication
attempts. By sending a specially crafted request, an attacker could exploit
this vulnerability to enumerate valid usernames.

CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
148397 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2019-1559
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by the failure to immediately close the TCP connection
after the hosts encounter a zero-length record with valid padding. An attacker
could exploit this vulnerability using a 0-byte record padding-oracle attack to
decrypt traffic.
