Descriptions

An issue was discovered in Asterisk Open Source 15.x before 15.4.1. When connected to Asterisk via TCP/TLS, if the client abruptly disconnects, or sends a specially crafted message, then Asterisk gets caught in an infinite loop while trying to read the data stream. This renders the system unusable.

Se ha descubierto un problema en Asterisk Open Source en versiones 15.x anteriores a la 15.4.1. Cuando se conecta a Asterisk vía TCP/TLS, si el cliente se desconecta abruptamente o envía un mensaje especialmente diseñado, entonces Asterisk queda atrapado en un bucle infinito mientras intenta leer el flujo de datos. Esto hace que el sistema se vuelva inutilizable.
