Description SMASH SMASH 2023-11-07 04:21:38 UTC

Squid is a caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. Due
to a NULL pointer dereference bug Squid is vulnerable to a Denial of Service
attack against Squid's Gopher gateway. The gopher protocol is always available
and enabled in Squid prior to Squid 6.0.1. Responses triggering this bug are
possible to be received from any gopher server, even those without malicious
intent. Gopher support has been removed in Squid version 6.0.1. Users are
advised to upgrade. Users unable to upgrade should reject all gopher URL
requests.
