"value": "CPython 3.9 and earlier doesn't disallow configuring an empty list (\"[]\") for SSLContext.set_npn_protocols() which is an invalid value for the underlying OpenSSL API. This results in a buffer over-read when NPN is used (see CVE-2024-5535 for OpenSSL). This vulnerability is of low severity due to NPN being not widely used and specifying an empty list likely being uncommon in-practice (typically a protocol name would be configured)."

Esto da como resultado una lectura excesiva del b\u00fafer cuando se utiliza NPN (consulte CVE-2024-5535 para OpenSSL). Esta vulnerabilidad es de baja gravedad debido a que NPN no se usa ampliamente y especificar una lista vac\u00eda probablemente sea poco com\u00fan en la pr\u00e1ctica (normalmente se configurar\u00eda un nombre de protocolo)."
