Descriptions

In Wireshark 3.2.0 to 3.2.6, 3.0.0 to 3.0.13, and 2.6.0 to 2.6.20, the TCP dissector could crash. This was addressed in epan/dissectors/packet-tcp.c by changing the handling of the invalid 0xFFFF checksum.

En Wireshark versiones 3.2.0 hasta 3.2.6, versiones 3.0.0 hasta 3.0.13 y versiones 2.6.0 hasta 2.6.20, el disector TCP podría bloquearse. Esto fue abordado en el archivo epan/disactors/packet-tcp.c mediante el cambio en el manejo del checksum 0xFFFF no válido
