How to fix?

There is no fixed version for RHEL:7 php-pspell.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php-pspell package and not the php-pspell package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

In PHP versions 7.2.x below 7.2.28, 7.3.x below 7.3.15 and 7.4.x below 7.4.3, when using file upload functionality, if upload progress tracking is enabled, but session.upload_progress.cleanup is set to 0 (disabled), and the file upload fails, the upload procedure would try to clean up data that does not exist and encounter null pointer dereference, which would likely lead to a crash.
