Posted by Carl Robert Blesius on

Just wanted to post this here, because I know of a couple of people use pound around here to create the illusion of running more than one OpenACS server on the same IP:PORT (e.g. I do -- the upgrade went smoothly.)

Two vulnerabilities have been discovered in Pound, a reverse proxy and
load balancer for HTTP. The Common Vulnerabilities and Exposures project
identifies the following problems:

* CVE-2005-3751:

HTTP requests with conflicting Content-Length and Transfer-Encoding

The old stable distribution (woody) does not contain pound packages.

For the stable distribution (sarge) these problems have been fixed in
