The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
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 changing the restrictions on file size.
