Thank you. However, it doesn't seem to fix the vulnerability, based on the above info and upstream's changelog.

CVE-2011-0520 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-0520):
  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.
