Descriptions

ConfBridge in Asterisk 11.x before 11.14.1 and Certified Asterisk 11.6 before 11.6-cert8 does not properly handle state changes, which allows remote attackers to cause a denial of service (channel hang and memory consumption) by causing transitions to be delayed, which triggers a state change from hung up to waiting for media.

ConfBridge en Asterisk 11.x anterior a 11.14.1 y Certified Asterisk 11.6 anterior a 11.6-cert8 no maneja debida mente los cambios de estado, lo que permite a atacantes remotos causar una denegación de servicio (cuelgue de canal y consumo de memoria) al causar que transiciones se retrasen, lo que provoca un cambio de estado de estar colgado a estar esperado medios.

Multiple vulnerabilities have been found in Asterisk, the worst of which could lead to Denial of Service, bypass intended ACL restrictions or allow an authenticated user to gain escalated privileges. Versions less than 11.14.2 are affected.
