Synopsis
The remote machine is affected by multiple vulnerabilities.Description
The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has krb5 packages installed that are affected by multiple vulnerabilities:- An authentication bypass flaw was found in the way krb5's certauth interface handled the validation of client certificates. A remote attacker able to communicate with the KDC could potentially use this flaw to impersonate arbitrary principals under rare and erroneous circumstances. (CVE-2017-7562)
