openssl: untrusted sender DN used as format string in CMP response validation

A flaw was found in OpenSSL. A malicious CMP Certificate Management Protocol endpoint can send an unexpected distinguished name DN directly as the format string argument to ERRraisedata, causing the application to dereference and write to unrelated stack contents. This can lead to a crash in the...
