What to do
AI-suggested
Apply the official patches provided by your vendor. For Ubuntu systems, update to squid version 7.7-0ubuntu0.26.04.2 or later. For Red Hat Enterprise Linux 8, update the squid:4 module to version 4.15-10.module+el8.10.0+25179+3c013c36.13 or later. Standard system updates will include these fixes. No additional mitigation steps are indicated by the vendor advisories.
Description
Multiple vulnerabilities have been identified in Squid, an open-source web proxy cache server. The primary issue involves incorrect handling of certain HTTP Transfer-Encoding headers, which could allow an attacker to perform HTTP request smuggling attacks, bypass security mechanisms, or poison web caches. These vulnerabilities affect various platforms including Unix and Windows. Fixes have been released by major vendors such as Ubuntu and Red Hat.
