How to fix?

There is no fixed version for RHEL:6 squid.

NVD Description

Note: Versions mentioned in the description apply only to the upstream squid package and not the squid package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

Squid 3.1.9 allows remote attackers to bypass the access configuration for the CONNECT method by providing an arbitrary allowed hostname in the Host HTTP header. NOTE: this issue might not be reproducible, because the researcher is unable to provide a squid.conf file for a vulnerable system, and the observed behavior is consistent with a squid.conf file that was (perhaps inadvertently) designed to allow access based on a "req_header Host" acl regex that matches www.uol.com.br
