Summary
A flaw was found in Squid. The limits applied for validation of HTTP response headers are applied before caching. However, Squid may grow a cached HTTP response header beyond the configured maximum size, causing a stall or crash of the worker process when a large header is retrieved from the disk cache, resulting in a denial of service.

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.

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.

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.

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.

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.

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.

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.

If this directive is not enabled, the Squid server is not vulnerable and no further mitigation is needed. 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.

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.

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.

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.

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.

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.
