In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is a NetScaler file parser infinite loop, triggered by a malformed capture file. This was addressed in wiretap/netscaler.c by validating record sizes.
Weakness
The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
