During the parsing of a ASN.1 sequence, a pointer in the linked list of
asn1_sequence is not initialized by asn1_get_sequence_of(). In case an
error occurs during parsing of the list, a situation is created where
the uninitialized pointer is passed to polarssl_free().
This sequence can be triggered when a PolarSSL entity is parsing a
certificate. So practically this means clients when receiving a
certificate from the server or servers in case they are actively asking
for a client certificate.
