Published: October 15, 2018 / Updated: June 8, 2025
PHP
Detailed vulnerability description
The vulnerability allows context-dependent attackers to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause (1) a denial of service (application crash) via a long string in the charset parameter, probably also requiring a long string in the str parameter; or (2) a denial of service (temporary application hang) via a long string in the str parameter.
