CWEhttps://cwe.mitre.org/data/definitions/674.html

In Wireshark 3.2.0 to 3.2.3, 3.0.0 to 3.0.10, and 2.6.0 to 2.6.16, the NFS dissector could crash. This was addressed in epan/dissectors/packet-nfs.c by preventing excessive recursion, such as for a cycle in the directory graph on a filesystem.

Weakness

The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
