Who is Vulnerable?
Vulnerability Description	Apache HTTP server is the most widely deployed web server on the Internet. Apache HTTP server is capable of running on a Microsoft Windows and wide variety of Unix-like platforms. A vulnerability exists in the Apache web server's Server Side Includes (SSI) functionality. A specially crafted file can trigger a memory buffer overflow. This condition allows a malicious user to stage an attack which may result in arbitrary code execution on the vulnerable system with the privileges of the Apache process. In case of an attack where code injection is not successful, the target Apache HTTP server will terminate the child process serving the attacker, closing the connection as a result. In case of an attack where code injection and execution is successful, an arbitrary code is executed with the privileges of the child process. The behavior of the target system will be dependent on the malicious code.
