The ldb_wildcard_compare function in ldb_match.c in ldb before 1.1.24, as
used in the AD LDAP server in Samba 4.x before 4.1.22, 4.2.x before 4.2.7,
and 4.3.x before 4.3.3, mishandles certain zero values, which allows remote
attackers to cause a denial of service (infinite loop) via crafted packets.
