Fix Recommendation

The RPM package management system can check the hashes of installed software packages, including many that are important to system security. Run the following command to list which files on the system have hashes that differ from what is expected by the RPM database:

# rpm -Va | awk '$1 ~ /..5/ && $2 != "c"'

If the file that has changed was not expected to, refresh from distribution media or online repositories.

rpm -Uvh [affected_package]

OR

yum reinstall [affected_package]

Check Contents

The following command will list which files on the system have file hashes different from what is expected by the RPM database:

# rpm -Va | awk '$1 ~ /..5/ && $2 != "c"'

If there is any output from the command for system binaries, verify that the changes were due to STIG application and have been documented with the ISSO.

If there are changes to system binaries and they are not documented with the ISSO, this is a finding.
