CVE-2020-28242

https://notcve.org/view.php?id=CVE-2020-28242

An issue was discovered in Asterisk Open Source 13.x before 13.37.1, 16.x before 16.14.1, 17.x before 17.8.1, and 18.x before 18.0.1 and Certified Asterisk before 16.8-cert5. If Asterisk is challenged on an outbound INVITE and the nonce is changed in each response, Asterisk will continually send INVITEs in a loop. This causes Asterisk to consume more and more memory since the transaction will never terminate (even if the call is hung up), ultimately leading to a restart or shutdown of Asterisk. Outbound authentication must be configured on the endpoint for this to occur. Se detectó un problema en Asterisk Open Source versiones 13.x anteriores a 13.37.1, versiones 16.x anteriores a 16.14.1, versiones 17.x anteriores a 17.8.1 y versiones 18.x anteriores a 18.0.1 y Certified Asterisk versiones anteriores a 16.8-cert5. • http://downloads.asterisk.org/pub/security/AST-2020-002.html https://lists.debian.org/debian-lts-announce/2022/04/msg00001.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/QUS54QTQCYKR36EIULYD544GXDA644HB • CWE-674: Uncontrolled Recursion •
