"value": "Asterisk is an open source private branch exchange and telephony toolkit. In Asterisk prior to versions 18.20.1, 20.5.1, and 21.0.1; as well as certified-asterisk prior to 18.9-cert6; Asterisk is susceptible to a DoS due to a race condition in the hello handshake phase of the DTLS protocol when handling DTLS-SRTP for media setup. This attack can be done continuously, thus denying new DTLS-SRTP encrypted calls during the attack. Abuse of this vulnerability may lead to a massive Denial of Service on vulnerable Asterisk servers for calls that rely on DTLS-SRTP. Commit d7d7764cb07c8a1872804321302ef93bf62cba05 contains a fix, which is part of versions 18.20.1, 20.5.1, 21.0.1, amd 18.9-cert6."

En Asterisk anteriores a las versiones 18.20.1, 20.5.1 y 21.0.1; as\u00ed como certificado-asterisco anterior a 18.9-cert6; Asterisk es susceptible a un DoS debido a una condici\u00f3n de ejecuci\u00f3n en la fase \"hello handshake\" del protocolo DTLS cuando maneja DTLS-SRTP para la configuraci\u00f3n de medios. Este ataque se puede realizar de forma continua, negando as\u00ed nuevas llamadas cifradas DTLS-SRTP durante el ataque. El abuso de esta vulnerabilidad puede provocar una denegaci\u00f3n de servicio masiva en servidores Asterisk vulnerables para llamadas que dependen de DTLS-SRTP. El commit d7d7764cb07c8a1872804321302ef93bf62cba05 contiene una soluci\u00f3n, que forma parte de las versiones 18.20.1, 20.5.1, 21.0.1, amd 18.9-cert6."
