How to fix?

Upgrade SLES:15.2 php7-openssl to version 7.4.6-3.6.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php7-openssl package and not the php7-openssl package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

In PHP versions 7.2.x below 7.2.33, 7.3.x below 7.3.21 and 7.4.x below 7.4.9, while processing PHAR files using phar extension, phar_parse_zipfile could be tricked into accessing freed memory, which could lead to a crash or information disclosure.
