Descriptions

netty-incubator-codec-ohttp is the OHTTP implementation for netty. BoringSSLAEADContext keeps track of how many OHTTP responses have been sent and uses this sequence number to calculate the appropriate nonce to use with the encryption algorithm. Unfortunately, two separate errors combine which would allow an attacker to cause the sequence number to overflow and thus the nonce to repeat.

netty-incubator-codec-ohttp es la implementación OHTTP para netty. BoringSSLAEADContext realiza un seguimiento de cuántas respuestas OHTTP se han enviado y utiliza este número de secuencia para calcular el nonce apropiado para usar con el algoritmo de cifrado. Desafortunadamente, se combinan dos errores separados que permitirían a un atacante provocar que el número de secuencia se desborde y, por lo tanto, que se repita el nonce.
