That depends on what you mean by "upgraded".

First we need someone to create and submit a code fix for the issues. 
After that passes our review process, supported versions will be fixed.


The Squid Software Foundation (the main Squid developers) only supports 
the latest "stable" release and some development, maybe a beta release.
  <https://www.squid-cache.org/Versions/>

Currently the supported versions are v7 (latest stable release series) 
and future-v8 (in development / "alpha" code). Once we call a version 
"fixed" you can expect to be able to download and build any later 
version and not see the problem.


Vendors distributing Squid make their own choices about which versions 
to release and support. That varies by which OS (and OS version) you 
use. They may provide binaries for a "fixed" Squid version, or patch an 
older version.

If you are building your own Squid you get to choose for yourself which 
type of upgrade to do.
