Descriptions

AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised implementation will not encrypt the entirety of the data under some circumstances. This could reveal sixteen bytes of data that was preexisting in the memory that wasn't written. In the special case of "in place" encryption, sixteen bytes of the plaintext would be revealed. Since OpenSSL does not support OCB based cipher suites for TLS and DTLS, they are both unaffected. Fixed in OpenSSL 3.0.5 (Affected 3.0.0-3.0.4). Fixed in OpenSSL 1.1.1q (Affected 1.1.1-1.1.1p).

El modo AES OCB para plataformas x86 de 32 bits que utilizan la implementación optimizada de ensamblaje AES-NI no cifrará la totalidad de los datos en algunas circunstancias. Esto podría revelar dieciséis bytes de datos que ya existían en la memoria y que no estaban escritos. En el caso especial del cifrado "in situ", se revelarían dieciséis bytes del texto sin formato. Dado que OpenSSL no es compatible con conjuntos de cifrado basados ??en OCB para TLS y DTLS, ambos no están afectados. Corregido en OpenSSL versión 3.0.5 (Afectado 3.0.0-3.0.4). Corregido en OpenSSL 1.1.1q (Afectado 1.1.1-1.1.1p)
