Amos,
Thank you for your reply.
I have version 3.5.12 compiled with Debian rules example provided here,
Do you think I could patch squid from 3.5.12 to 3.5.21 via patches available at http://www.squid-cache.org/Versions/v3/3.5/
Or I could download tar.gz file and replace files from that folder to Debian source folder ?
do i need any extra tools to build squid 3.5.21?

When re-building your Squid with SSL-Bump features it is important to
always use teh very latest Squid release. SSL/TLS and bumping are part
of an ongoing arms race situation. Things are constantly changing and
software from as little as a year ago is unlikly to work 100% well with
intercepting ('bumping') encryption from today.
First thing to try is to rebuild with squid 3.5.20 or .21 and see if the
problem remains.
