NVD Description

Note: Versions mentioned in the description apply only to the upstream libecap-devel package and not the libecap-devel package as distributed by RHEL.

An issue was discovered in Squid before 4.9. When handling a URN request, a corresponding HTTP request is made. This HTTP request doesn't go through the access checks that incoming HTTP requests go through. This causes all access checks to be bypassed and allows access to restricted HTTP servers, e.g., an attacker can connect to HTTP servers that only listen on localhost.
