High impact if exploited, but EPSS currently rates exploitation as unlikely (2.30%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In Wireshark 2.4.0 to 2.4.5 and 2.2.0 to 2.2.13, the LWAPP dissector could crash. This was addressed in epan/dissectors/packet-lwapp.c by limiting the encapsulation levels to restrict the recursion depth.
