Description
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to the trailing 1-15 bytes of a message may be exposed in cleartext on encryption and are not covered by the authentication tag. When using the low-level OCB API directly with AES-NI or other hardware-accelerated code paths, inputs whose length is not a multiple of 16 bytes can leave the final partial block unencrypted and unauthenticated. A remote attacker can intercept traffic and gain access to potentially sensitive information.
