polarssl -- Remote attack using crafted certificates

PolarSSL team reports:

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.
