freeradius: insufficient CRL validation

The FreeRADIUS server relies on OpenSSL to perform certificate validation, including Certificate Revocation List CRL checks. The FreeRADIUS usage of OpenSSL, in CRL application, limits the checks to leaf certificates, therefore not detecting revocation of intermediate CA certificates. An unexpire...

OpenJDK: incorrect OCSP nextUpdate checking (Libraries, 8075374)

A flaw was found in the way the Libraries component of OpenJDK verified Online Certificate Status Protocol OCSP responses. An OCSP response with no nextUpdate date specified was incorrectly handled as having unlimited validity, possibly causing a revoked X.509 certificate to be interpreted as val...
