Vendor and ecosystem advisories describing this.

RHSA-2002:129Red Hat Security Advisory: php security update2002-06-26csaf · redhat_csafUS
PHP versions earlier than 4.1.0 contain a vulnerability that could allow arbitrary commands to be executed. [updated 22 Aug 2002] The initial set of errata packages contained an incorrect set of dependencies. This meant that a number of packages would need to be installed before php that were not essential to the operation of php. Updated errata packages are included with this advisory that have corrected dependencies.
