CVE-2007-3998: The wordwrap function in PHP 4 before 4.4.8, and PHP 5 before 5.2.4, does not properly use the breakcharlen...

Security readout for executives and security teams

This is an old PHP denial-of-service flaw. If an application on affected PHP versions lets outside input influence wordwrap arguments, a request could crash the application or cause it to hang. The bundle does not show data theft or code execution impact. Most likely exposure is legacy PHP 4.x or early PHP 5.x systems, including distribution packages referenced by vendor advisories, where web-facing code uses wordwrap with attacker-influenced arguments. Treat as a legacy-platform cleanup issue unless affected PHP versions still run business services. Prioritize internet-facing systems because the documented impact is service disruption, not confidentiality compromise. Mitigation focus: Upgrade PHP 4 to 4.4.8 or later where still applicable.; Upgrade PHP 5 to 5.2.4 or later where still applicable.; Apply vendor security updates from the relevant Linux distribution advisory..
