Squid is a caching and forwarding web proxy.
An end of life version of Squid proxy was detected on the host. The Squid proxy is officially supported for the latest available version only. Since there will be no further bug fixes or security updates for this version, it is recommended that you migrate to the latest supported Squid release.
The system is at high risk of being exposed to security vulnerabilities. Since the vendor no longer provides updates, obsolete software is more vulnerable to viruses and other attacks.
Customers are advised to update to the latest supported version of Squid. More information can be obtained here.
