acl.c in Tinyproxy before 1.8.3, when an Allow configuration setting specifies a CIDR block, permits TCP connections from all IP addresses, which makes it easier for remote attackers to hide the origin of web traffic by leveraging the open HTTP proxy server.

- Update to upstream 1.83

    - switch to using systemd macros in rpm

    - update to a PIE hardened build

    - update to use systemd

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Christoph Martin discovered that incorrect ACL processing in TinyProxy, a lightweight, non-caching, optionally anonymizing HTTP proxy, could lead to unintended network access rights.

The oldstable distribution (lenny) is not affected.

When including a line to allow a network of IP addresses, the access to tinyproxy 56 is actually allowed for all IP addresses.
