      "value": "oqs-provider is a provider for the OpenSSL 3 cryptography library that adds support for post-quantum cryptography in TLS, X.509, and S/MIME using post-quantum algorithms from liboqs. Flaws have been identified in the way oqs-provider handles lengths decoded with DECODE_UINT32 at the start of serialized hybrid (traditional + post-quantum) keys and signatures. Unchecked length values are later used for memory reads and writes; malformed input can lead to crashes or information leakage. Handling of plain/non-hybrid PQ key operation is not affected. This issue has been patched in in v0.6.1. All users are advised to upgrade. There are no workarounds for this issue."

Se han identificado fallas en la forma en que oqs-provider maneja las longitudes decodificadas con DECODE_UINT32 al inicio de firmas y claves h\u00edbridas serializadas (tradicionales + poscu\u00e1nticas). Los valores de longitud no verificados se utilizan posteriormente para lecturas y escrituras de memoria; La entrada mal formada puede provocar fallas o fugas de informaci\u00f3n. El manejo de la operaci\u00f3n de clave PQ simple/no h\u00edbrida no se ve afectado. Este problema se solucion\u00f3 en la versi\u00f3n 0.6.1. Se recomienda a todos los usuarios que actualicen. No existen workarounds para este problema."
