    "summary": "A buffer overflow was found in the Apache proxy module, mod_proxy, which can be triggered by receiving an invalid Content-Length header. In order to exploit this issue an attacker would need to get an Apache installation that was configured as a proxy to connect to a malicious site. This would cause the Apache child processing the request to crash, although this does not represent a significant Denial of Service attack as requests will continue to be handled by other Apache child processes. This issue may lead to remote arbitrary code execution on some BSD platforms.",
