Descriptions
The rsa_verify_hash_ex function in rsa_verify_hash.c in LibTomCrypt, as used in OP-TEE before 2.2.0, does not validate that the message length is equal to the ASN.1 encoded data length, which makes it easier for remote attackers to forge RSA signatures or public certificates by leveraging a Bleichenbacher signature forgery attack.
La función rsa_verify_hash_ex en rsa_verify_hash.c en LibTomCrypt, como se utiliza en OP-TEE en versiones anteriores a 2.2.0, no valida que la longitud del mensaje es igual a la longitud de datos codificados en ASN.1, lo que facilita a atacantes remotos falsificar firmas RSA o certificados públicos aprovechando un ataque de falsificación de firma de Bleichenbacher.
