CVE-2016-1000108 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:20.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream yaws package and not the yaws package as distributed by Ubuntu.
yaws before 2.0.4 does not attempt to address RFC 3875 section 4.1.18 namespace conflicts and therefore does not protect CGI applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect a CGI application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue.
