Description of the vulnerability

The HP LoadRunner and HP Performance Center products install the magentproc.exe process. It listens on ports 5001/tcp and 5002/tcp, when HttpTunnel is enabled.

However, the process does not check the allocation size requested by the client. A malicious client can thus request a short memory area, in order to create an overflow.

An attacker can therefore generate a buffer overflow in the magentproc.exe process, in order to execute code with SYSTEM privileges.
