In OpenSSL 1.1.0 before 1.1.0c, applications parsing invalid CMS structures
can crash with a NULL pointer dereference. This is caused by a bug in the
handling of the ASN.1 CHOICE type in OpenSSL 1.1.0 which can result in a
NULL value being passed to the structure callback if an attempt is made to
free certain invalid encodings. Only CHOICE structures using a callback
which do not handle NULL value are affected.
