      "value": "Botan is a C++ cryptography library. X.509 certificates can identify elliptic curves using either an object identifier or using explicit encoding of the parameters.  Prior to 3.5.0 and 2.19.5, checking name constraints in X.509 certificates is quadratic in the number of names and name constraints. An attacker who presented a certificate chain which contained a very large number of names in the SubjectAlternativeName, signed by a CA certificate which contained a large number of name constraints, could cause a denial of service. The problem has been addressed in Botan 3.5.0 and a partial backport has also been applied and is included in Botan 2.19.5."

Los certificados X.509 pueden identificar curvas el\u00edpticas utilizando un identificador de objeto o una codificaci\u00f3n expl\u00edcita de los par\u00e1metros. Antes de 3.5.0 y 2.19.5, la verificaci\u00f3n de las restricciones de nombres en los certificados X.509 era cuadr\u00e1tica en el n\u00famero de nombres y restricciones de nombres. Un atacante que presentara una cadena de certificados que contuviera una gran cantidad de nombres en el SubjectAlternativeName, firmado por un certificado de CA que contuviera una gran cantidad de restricciones de nombres, podr\u00eda provocar una denegaci\u00f3n de servicio. El problema se solucion\u00f3 en Botan 3.5.0 y tambi\u00e9n se aplic\u00f3 un backport parcial que se incluye en Botan 2.19.5."
