CVE-2019-9208

In Wireshark 2.4.0 to 2.4.12 and 2.6.0 to 2.6.6, the TCAP dissector could crash. This was addressed in epan/dissectors/asn1/tcap/tcap.cnf by avoiding NULL pointer dereferences.

Weakness

A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
