Descriptions

murmur in Mumble through 1.2.19 before 2018-08-31 mishandles multiple concurrent requests that are persisted in the database, which allows remote attackers to cause a denial of service (daemon hang or crash) via a message flood.

murmur en Mumble, hasta la versión 1.2.19 antes del 31/08/2018, gestiona de manera incorrecta múltiples peticiones concurrentes que persisten en la base de datos, lo que permite a los atacantes remotos provocar una denegación de servicio (bloqueo o cierre inesperado del demonio) mediante una inundación de mensajes.
