A buffer overflow in Wireshark before 4.2.0 allows a remote attacker to cause a denial of service via the pan/addr_resolv.c, and ws_manuf_lookup_str(), size components. NOTE: this is disputed by the vendor because neither release 4.2.0 nor any other release was affected.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
