Secure testing team - Apr 2011 - Bug#621493: tinyproxy: allows everyone if using network addresses in Allow rule

Package: tinyproxy
Version: 1.8.2-1
Severity: grave
Tags: upstream security squeeze patch
Justification: user security hole

When including a line like

Allow 192.168.0.0/16

to allow a network of ip addresses instead of only one ip 
address per line the access to tinyproxy
is actually allowed for all ip addresses.

This makes tinyproxy usable as an open proxy from everywhere
in the internet.

This bug was reported upstream nearly a year ago:

https://banu.com/bugzilla/show_bug.cgi?id=90

and includes a fix there.
