OpenSSL -- NULL pointer de-reference

The OpenSSL project reports:

EDIPARTYNAME NULL pointer de-reference (High)
The X.509 GeneralName type is a generic type for representing
different types of names. One of those name types is known as
EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which
compares different instances of a GENERAL_NAME to see if they
are equal or not. This function behaves incorrectly when both
GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer
dereference and a crash may occur leading to a possible denial
of service attack.
