Synopsis ========
Pound is vulnerable to HTTP request smuggling, which could be exploited to bypass security restrictions or poison web caches.
Background ==========
Pound is a reverse proxy, load balancer and HTTPS front-end. It allows to distribute the load on several web servers and offers a SSL wrapper for web servers that do not support SSL directly.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-servers/pound < 2.0.5 >= 2.0.5
Description ===========
Pound fails to handle HTTP requests with conflicting "Content-Length" and "Transfer-Encoding" headers correctly.
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.
Resolution ==========
All Pound users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-servers/pound-2.0.5"
