HTTP: PHP htmlspecialchars htmlentities Buffer Overflow
This signature detects attempts to exploit a known vulnerability in PHP. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the affected application.
Extended Description
PHP is prone to a buffer-overflow vulnerability because it fails to perform boundary checks before copying user-supplied data to insufficiently sized memory buffers. An attacker can exploit this issue to execute arbitrary machine code in the context of the PHP process. Failed exploit attempts will likely crash the webserver, denying service to legitimate users. PHP 5.4 is vulnerable; other versions may also be affected.
