"value": "BigBlueButton is an open source web conferencing system. Versions starting with 2.2 and prior to 2.3.19, 2.4.7, and 2.5.0-beta.2 are vulnerable to regular expression denial of service (ReDoS) attacks. By using specific a RegularExpression, an attacker can cause denial of service for the bbb-html5 service. The useragent library performs checking of device by parsing the input of User-Agent header and lets it go through lookupUserAgent() (alias of useragent.lookup() ). This function handles input by regexing and attackers can abuse that by providing some ReDos payload using `SmartWatch`. The maintainers removed `htmlclient/useragent` from versions 2.3.19, 2.4.7, and 2.5.0-beta.2. As a workaround, disable NginX forwarding the requests to the handler according to the directions in the GitHub Security Advisory."

Las versiones a partir de 2.2 y anteriores a 2.3.19, 2.4.7 y 2.5.0-beta.2 son vulnerables a ataques de denegaci\u00f3n de servicio con expresiones regulares (ReDoS). Usando una RegularExpression espec\u00edfica, un atacante puede causar una denegaci\u00f3n de servicio para el servicio bbb-html5. La biblioteca useragent lleva a cabo una comprobaci\u00f3n del dispositivo al analizar la entrada del encabezado User-Agent y la hace pasar por lookupUserAgent() (alias de useragent.lookup() ). Esta funci\u00f3n maneja la entrada mediante regexing y atacantes pueden abusar de ello al proporcionar alguna carga \u00fatil ReDos usando \"SmartWatch\". Los mantenedores han eliminado \"htmlclient/useragent\" de las versiones 2.3.19, 2.4.7 y 2.5.0-beta.2.
