A use-after-free in res_pjsip_pubsub.c in Sangoma Asterisk 16.28, 18.14, 19.6, and certified/18.9-cert2 may allow a remote authenticated attacker to crash Asterisk (denial of service) by performing activity on a subscription via a reliable transport at the same time that Asterisk is also performing activity on that subscription.

res_pjsip_t38 in Sangoma Asterisk 16.x before 16.16.2, 17.x before 17.9.3, and 18.x before 18.2.2, and Certified Asterisk before 16.8-cert7, allows an attacker to trigger a crash by sending an m=image line and zero port in a response to a T.38 re-invite initiated by Asterisk. This is a re-occurrence of the CVE-2019-15297 symptoms but not for exactly the same reason. The crash occurs because there is an append operation relative to the active topology, but this should instead be a replace operation. La función res_pjsip_t38 en Sangoma Asterisk versiones 16.x anteriores a 16.16.2, 17.x anteriores a 17.9.3, y 18.x anteriores a 18.2.2, y Certified Asterisk anteriores a 16.8-cert7, permite a un atacante desencadenar un fallo mediante el envío de una línea m=image y un puerto cero en una respuesta a una Re invitación T.38 iniciada por Asterisk. Se trata de una reaparición de los síntomas de la CVE-2019-15297 pero no exactamente por el mismo motivo. • https://downloads.asterisk.org/pub/security/AST-2021-006.html https://lists.debian.org/debian-lts-announce/2022/11/msg00021.html https://www.debian.org/security/2022/dsa-5285 • CWE-476: NULL Pointer Dereference •

An issue was discovered in Asterisk through 19.x. When using STIR/SHAKEN, it is possible to download files that are not certificates. These files could be much larger than what one would expect to download, leading to Resource Exhaustion. This is fixed in 16.25.2, 18.11.2, and 19.3.2. Se ha detectado un problema en Asterisk versiones hasta 19.x. • http://packetstormsecurity.com/files/166744/Asterisk-Project-Security-Advisory-AST-2022-001.html http://packetstormsecurity.com/files/172139/Shannon-Baseband-chatroom-SDP-Attribute-Memory-Corruption.html https://downloads.asterisk.org/pub/security https://downloads.asterisk.org/pub/security/AST-2022-001.html https://lists.debian.org/debian-lts-announce/2022/11/msg00021.html https://www.debian.org/security/2022/dsa-5285 • CWE-400: Uncontrolled Resource Consumption •
