For more information about the mitigation, see the mitigation section below.\n\nThe `cache_dir` directive is disabled by default in Squid shipped in Red Hat Enterprise Linux 6, 7, 8 and 9. Therefore, these Red Hat Enterprise Linux versions are not vulnerable with the default configuration.\n\nRed Hat is not planning to address this issue in Red Hat Enterprise Linux 6 and 7 due to the changes required and the magnitude of the differences between Squid 3 and 4 code bases, backporting the changes to the Squid 3 code base has not been feasible.\n\nWe recommend that customers using Squid as a caching proxy on Red Hat Enterprise Linux 6 and 7 to upgrade to Red Hat Enterprise Linux 8 and 9 to use Squid version 4 or version 5, respectively.
