A remote attacker could use an\nempty password to authenticate to servers that were believed to have\npassword login disabled. (CVE-2017-7546)\n\nJeff Janes discovered that PostgreSQL incorrectly handled the\npg_user_mappings catalog view. A remote attacker without server privileges\ncould possibly use this issue to obtain certain passwords.
