=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS
- Ubuntu 21.10
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS

Summary:

OpenSSL could be made to expose sensitive information over the network.

Software Description:
- openssl: Secure Socket Layer (SSL) cryptographic library and tools

Details:

Alex Chernyakhovsky discovered that OpenSSL incorrectly handled AES OCB
mode when using the AES-NI assembly optimized implementation on 32-bit
x86 platforms. A remote attacker could possibly use this issue to obtain
sensitive information.
