Descriptions

lib/gnutls_pk.c in libgnutls in GnuTLS 2.5.0 through 2.6.5 generates RSA keys stored in DSA structures, instead of the intended DSA keys, which might allow remote attackers to spoof signatures on certificates or have unspecified other impact by leveraging an invalid DSA key.

lib/gnutls_pk.c en libgnutls en GnuTLS v2.5.0 hasta v2.6.5 genera claves RSA almacenados en estructuras DSA, en lugar de las claves DSA previstas, lo cual podría permitir a atacantes remotos suplantar firmas en los certificados o tener otro impacto no especificado por el utilizamiento de una clave DSA no es válida.
