NVD Description

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

In PHP 8.0.X before 8.0.28, 8.1.X before 8.1.16 and 8.2.X before 8.2.3, core path resolution function allocate buffer one byte too small. When resolving paths with lengths close to system MAXPATHLEN setting, this may lead to the byte after the allocated buffer being overwritten with NUL value, which might lead to unauthorized data access or modification.
