Synopsis

The remote Debian host is missing a security update.

Description

Due to improper input validation, Squid is vulnerable to an HTTP Request Smuggling attack.

This problem allows a trusted client to perform HTTP Request Smuggling and access services otherwise forbidden by Squid security controls.

For Debian 9 stretch, this problem has been fixed in version 3.5.23-5+deb9u6.

We recommend that you upgrade your squid3 packages.
