The attacker should be an authorized user of the product to perform this attack. Users are recommended to upgrade to version 4.0.0, which fixes this issue.\n\nThe problem occurs when an application doesn’t use a constant-time algorithm for validating a signature. The method Arrays.equals() returns false right away when it sees that one of the input’s bytes are different. It means that the comparison time depends on the contents of the arrays. This little thing may allow an attacker to forge a valid signature for an arbitrary message byte by byte. So it might allow malicious users to submit splits/work with selected signatures to LLAP without running as a privileged user, potentially leading to DDoS attack.\n\nMore details in the reference section."},{"lang":"es","value":"El uso de Arrays.equals() en LlapSignerImpl en Apache Hive para comparar firmas de mensajes permite a un atacante falsificar una firma válida para un mensaje arbitrario byte a byte.

El problema ocurre cuando una aplicación no utiliza un algoritmo de tiempo constante para validar una firma. El método Arrays.equals() devuelve falso de inmediato cuando ve que uno de los bytes de entrada es diferente. Significa que el tiempo de comparación depende del contenido de las matrices. Esta pequeña cosa puede permitir a un atacante falsificar una firma válida para un mensaje arbitrario byte a byte. Por lo tanto, podría permitir que los usuarios malintencionados envíen divisiones/trabajos con firmas seleccionadas a LLAP sin ejecutarse como un usuario privilegiado, lo que podría conducir a un ataque DDoS.
