PHP HTML entity encoder htmlentities() and htmlspecialchars() buffer overflow
| php-htmlentities-bo (29971) |  High Risk |
Description:
PHP is vulnerable to a buffer overflow, caused by improper bounds checking by the htmlentities() and htmlspecialchars() HTML entity encoder functions. By sending a specially-crafted request containing embedded Greek theta UTF-8 characters to a PHP-based Web application that utilizes the vulnerable functions, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
