Descriptions

In Wireshark 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the SIGCOMP dissector could go into an infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-sigcomp.c by correcting a memory-size check.

En Wireshark 2.2.0 a 2.2.5 y 2.0.0 a 2.0.11, el disector SIGCOMP podría entrar en un bucle infinito, desencadenado por un paquete de inyección o un archivo de captura mal formado. Esto se trató en epan/dissectors/packet-sigcomp.c mediante la corrección de una comprobación del tamaño de la memoria.
