In Wireshark 3.0.0, the GSUP dissector could go into an infinite loop. This was addressed in epan/dissectors/packet-gsm_gsup.c by rejecting an invalid Information Element length.
Weakness
The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
