NVD Description

Note: Versions mentioned in the description apply only to the upstream php:7.4/php-ffi package and not the php:7.4/php-ffi package as distributed by AlmaLinux. See How to fix? for AlmaLinux:8 relevant fixed versions and status.

In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when AES-CCM mode is used with openssl_encrypt() function with 12 bytes IV, only first 7 bytes of the IV is actually used. This can lead to both decreased security and incorrect encryption data.
