Descriptions
GnuTLS before 3.3.13 does not validate that the signature algorithms match when importing a certificate.
GnuTLS versiones anteriores a 3.3.13, no comprueba que los algoritmos de firma coincidan cuando se importa un certificado.
It was discovered that GnuTLS did not check if all sections of X.509 certificates indicate the same signature algorithm. This flaw, in combination with a different flaw, could possibly lead to a bypass of the certificate signature check.
