Fixed In Version: scap-security-guide-0.1.35-1.el7 Doc Type: Known Issue
Doc Text:
The `ensure_gpgcheck_repo_metadata` rule fails During remediation of the `ensure_gpgcheck_repo_metadata` rule, certain profiles update the `yum.conf` file to enable the `repo_gpgcheck` option. Red Hat does not currently provide signed repository metadata. As a consequence, the *yum* utility is no longer able to install any package from official repositories. To work around the problem, use a tailoring file to remove `ensure_gpgcheck_repo_metadata` from the profile. If remediation already breaks the system, update `yum.conf` and set `repo_gpgcheck` to `0`.

Description Marek Haicman 2017-06-27 23:08:07 UTC
Description of problem:
With this rule enforced, yum only installs packages from repositories with signed metadata. Red Hat currently does not provide such repositories, thus by enabling this option, machine effectively loses ability to update packages. From the security standpoint, this is bad thing. Proposal is to leave it failing, with notice for users explaining situation.

Version-Release number of selected component (if applicable):
scap-security-guide-0.1.33-5.el7.noarch

How reproducible:
reliably

Steps to Reproduce:
1. perform remediation of rule_ensure_gpgcheck_repo_metadata
2. try to install something from Red Hat repository
3.

Actual results:
1) is remedied
2) fails

Expected results:
1) is not remedied, explanation is given that Red Hat does not support this right now
2) is successful

Comment 1 Marek Haicman 2017-06-27 23:11:24 UTC
Note: this might prevent full profile remediation of profiles containing this rule (profile_stig-rhel7-disa)

Comment 2 Watson Yuuma Sato 2017-11-16 13:08:09 UTC
This is already fixed upstream by https://github.com/OpenSCAP/scap-security-guide/pull/2189.

Comment 4 Marek Haicman 2018-01-22 12:37:14 UTC
Verified in version scap-security-guide-0.1.36-7.el7 no remediation is performed
