Description

AES OCB fails to encrypt some bytes

Details
Package openssl-src
Version 111.21.0+1.1.1p
URL https://www.openssl.org/news/secadv/20220705.txt
Date 2022-07-05
Patched versions >=111.22, <300.0,>=300.0.9

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.

See advisory page for additional details.
