This signature detects attempts to exploit a known vulnerability against the Apache daemon with PHP support. Apache 1.3.x with php_4.0.6 is vulnerable. Attackers can send a multipart/form-data POST request to crash the Apache daemon process.
A vulnerability has been reported for PHP versions 4.2.0 and 4.2.1. It is possible for a remote attacker to cause the PHP interpreter to crash the web server on a vulnerable system and execute malicious, attacker supplied code. The vulnerability is the result of the PHP interpreter incorrectly parsing MIME headers when HTTP POST commands are received. When PHP receives a malformed POST request, it generates an error condition that is improperly handled. As a result, the attacker may cause the web server to crash and possibly execute supplied code.
