Fix various denial of service attacks:

CVE-2014-3487

  The cdf_read_property_info function does not properly validate a stream
  offset, which allows remote attackers to cause a denial of service
  (application crash) via a crafted CDF file.

CVE-2014-3480

  The cdf_count_chain function in cdf.c in does not properly validate
  sector-count data, which allows remote attackers to cause a denial of 
service
  (application crash) via a crafted CDF file.

CVE-2014-3479

  The cdf_check_stream_offset function in cdf.c relies on incorrect
  sector-size data, which allows remote attackers to cause a denial of service 
  (application crash) via a crafted stream offset in a CDF file.

CVE-2014-3478

  Buffer overflow in the mconvert function in softmagic.c allows remote
  attackers to cause a denial of service (application crash) via a crafted
  Pascal string in a FILE_PSTRING conversion.

CVE-2014-0238

  The cdf_read_property_info function in cdf.c allows remote attackers to
  cause a denial of service (infinite loop or out-of-bounds memory access) via
  a vector that (1) has zero length or (2) is too long.

CVE-2014-0237

  The cdf_unpack_summary_info function in cdf.c allows remote attackers to
  cause a denial of service (performance degradation) by triggering many
  file_printf calls.

CVE-2014-0207

  The cdf_read_short_sector function in cdf.c allows remote attackers to
  cause a denial of service (assertion failure and application exit) via a
  crafted CDF file.
