Descripción |
|
|
Se han descubierto múltiples vulnerabilidades en GNU-TLS versión anterior a 1.0.2.8. La vulnerabilidad reside en la manera que la librería "libtasn1" decodifica el subconjunto de ASN.1 "DER" al manejar certificados X.509 inválidos. Un atacante remoto podría causar una denegación de servicio mediante un certificado X.509 especialmente diseñado. No se sabe si esta vulnerabilidad también podría permitir ejecución de código arbitrario. |
