Descriptions

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.

En Wireshark versiones 3.2.0 hasta 3.2.3, 3.0.0 hasta 3.0.10 y 2.6.0 hasta 2.6.16, el disector NFS podría bloquearse. Esto se abordó en el archivo epan/dissectors/packet-nfs.c impidiendo la recurrencia excesiva, como por ejemplo, un ciclo en el gráfico de directorio en un sistema de archivos.
