NVD Description

Note: Versions mentioned in the description apply only to the upstream squid3 package and not the squid3 package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 relevant fixed versions and status.

mime_header.cc in Squid before 3.5.18 allows remote attackers to bypass intended same-origin restrictions and possibly conduct cache-poisoning attacks via a crafted HTTP Host header, aka a "header smuggling" issue.
