commit ee5a1253285e5c9f406c8b57b0686319b70c07d8
Author: Dr. Stephen Henson <steve@openssl.org>
Date:   Mon Mar 9 23:11:45 2015 +0000

Fix ASN1_TYPE_cmp
    
    Fix segmentation violation when ASN1_TYPE_cmp is passed a boolean type. This
    can be triggered during certificate verification so could be a DoS attack
    against a client or a server enabling client authentication.
