Descriptions

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.

A vulnerability was found in PHP. This security issue occurs because the core path resolution function allocates a buffer one byte small. Resolving paths with lengths close to the system MAXPATHLEN setting may lead to the byte after the allocated buffer being overwritten with a NULL value, which might lead to unauthorized data access or modification.
