Descriptions
res_pjsip_t38 in Sangoma Asterisk 15.x before 15.7.4 and 16.x before 16.5.1 allows an attacker to trigger a crash by sending a declined stream in a response to a T.38 re-invite initiated by Asterisk. The crash occurs because of a NULL session media object dereference.
res_pjsip_t38 en Sangoma Asterisk 15.x antes de 15.7.4 y 16.x antes de 16.5.1 permite a un atacante desencadenar un fallo enviando un flujo rechazado en una respuesta a una reinvitación T.38 iniciada por Asterisk. El fallo se produce debido a una derivación de objeto de medios de sesión NULL.
When Asterisk sends a re-invite initiating T.38 faxing and the endpoint responds with a m=image line and zero port, a crash will occur in Asterisk. This is a re-occurrence of AST-2019-004.
