The compress_add_dlabel_points function in dns/Compress.c in MaraDNS
1.4.03, 1.4.05, and probably other versions allows remote attackers to
cause a denial of service (segmentation fault) and possibly execute
arbitrary code via a long DNS hostname with a large number of labels,
which triggers a heap-based buffer overflow.
