Synopsis
========

Multiple vulnerabilities have been found in Squid, the worst of which
could lead to arbitrary code execution.

Background

Squid is a full-featured Web proxy cache designed to run on Unix
systems. It supports proxying and caching of HTTP, FTP, and other URLs,
as well as SSL support, cache hierarchies, transparent caching, access
control lists and many other features.
