Descriptions

Due to failure in validating the length provided by an attacker-crafted MSMMS packet, Wireshark version 4.0.5 and prior, in an unusual configuration, 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 en un paquete manipulado MSMMS, Wireshark v4.0.5 y anteriores, en una configuración inusual, es susceptible a un desbordamiento de búfer de pila, y posiblemente a la ejecución de código en el contexto del proceso que ejecuta Wireshark.

Multiple vulnerabilities have been found in Wireshark, the worst of which could result in denial of service. Versions greater than or equal to 4.0.6 are affected.
