NVD Description

Note: Versions mentioned in the description apply only to the upstream php:8.3/php-xml package and not the php:8.3/php-xml package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

In PHP versions 8.2.* before 8.2.32, 8.3.* before 8.3.32, 8.4.* before 8.4.23, 8.5.* before 8.5.8, the AES-WRAP-PAD algorithm implementation in OpenSSL extension contains a buffer allocation flaw. The output buffer for the AES key-wrap-with-padding operation is sized from the plaintext length without accounting for RFC 5649 expansion. This may cause OpenSSL to write beyond allocated memory, corrupting heap metadata and triggering application abort.
