Descriptions

Due to failure in validating the length provided by an attacker-crafted IEEE-C37.118 packet, Wireshark version 4.0.5 and prior, by default, is susceptible to a heap-based buffer overflow, and possibly code execution in the context of the process running Wireshark.

Debido a un fallo en la validación de la longitud proporcionada por un atacante de paquetes IEEE-C37.118, Wireshark v4.0.5 y anteriores, por defecto, es susceptible a un desbordamiento de búfer de la pila, y posiblemente la ejecución de código en el contexto del proceso que ejecuta Wireshark.

A flaw was found in the IEEE C37.118 Synchrophasor dissector of Wireshark. This issue occurs when decoding malformed packets from a pcap file or from the network, causing a buffer overflow, resulting in a denial of service.
