Descriptions
ssl3_get_record in s3_pkt.c for OpenSSL before 0.9.7a and 0.9.6 before 0.9.6i does not perform a MAC computation if an incorrect block cipher padding is used, which causes an information leak (timing discrepancy) that may make it easier to launch cryptographic attacks that rely on distinguishing between padding and MAC verification errors, possibly leading to extraction of the original plaintext, aka the "Vaudenay timing attack."
ssl3_get_record en s3_ptk.c de OpenSSL anteriores a 0.9.7a y 0.9.6 anteriores a 0.9.6i no realiza un cálculo MAC si un relleno de bloque de cifra incorrecto es usado, lo que causa una fuga de información (discrepancia en temporización) que puede hacer más fácil lanzar ataques criptográficos que dependan de distinguir entren errores de relleno o de verificación de MAC, posiblemente conducentes a la extracción del texto plano original, también conocida como "Ataque de temporización de Vaudenay".
