Background ========== Pound is a reverse proxy, load balancer and HTTPS front-end.

Impact ====== An attacker could exploit this vulnerability by sending HTTP requests with specially crafted "Content-Length" and "Transfer-Encoding" headers to bypass certain security restrictions or to poison the web proxy cache. Workaround ========== There is no known workaround at this time.
