DESCRIPTION:
Thomas Reifferscheid has reported a vulnerability in Adzapper, which
potentially can be exploited by malicious people to cause a DoS
(Denial of Service).

The vulnerability is caused due to an error in the "squid_redirect"
script when handling URLs that contain a large number of forward
slashes. This can be exploited to cause squid to consume large amount
of CPU resources, potentially causing a DoS.
