package/wireshark: security bump to version 3.2.7

- Fix CVE-2020-25862: In Wireshark 3.2.0 to 3.2.6, 3.0.0 to 3.0.13, and
  2.6.0 to 2.6.20, the TCP dissector could crash. This was addressed in
  epan/dissectors/packet-tcp.c by changing the handling of the invalid
  0xFFFF checksum.
- Fix CVE-2020-25863: In Wireshark 3.2.0 to 3.2.6, 3.0.0 to 3.0.13, and
  2.6.0 to 2.6.20, the MIME Multipart dissector could crash. This was
  addressed in epan/dissectors/packet-multipart.c by correcting the
  deallocation of invalid MIME parts.
- Fix CVE-2020-25866: In Wireshark 3.2.0 to 3.2.6 and 3.0.0 to 3.0.13,
  the BLIP protocol dissector has a NULL pointer dereference because a
  buffer was sized for compressed (not uncompressed) messages. This was
  addressed in epan/dissectors/packet-blip.c by allowing reasonable
  compression ratios and rejecting ZIP bombs.
