caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. Affected versions of squid are subject to a a Use-After-Free bug which can lead to a Denial of Service attack via collapsed forwarding. All versions of Squid from 3.5 up to and including 5.9 configured with \"collapsed_forwarding on\" are vulnerable. Configurations with \"collapsed_forwarding off\" or without a \"collapsed_forwarding\" directive are not vulnerable. This bug is fixed by Squid version 6.0.1. Users are advised to upgrade.
