Description

A flaw was found in OpenSSL. When applications directly call the low-level CRYPTO_ocb128_encrypt() or CRYPTO_ocb128_decrypt() functions with non-block-aligned lengths in a single call on hardware-accelerated builds, the trailing 1-15 bytes of a message may be exposed in cleartext. These exposed bytes are not covered by the authentication tag, allowing an attacker to read or tamper with them without detection.
