RHEL-09-214030 - RHEL 9 must be configured so that the cryptographic hashes of system files match vendor values.

The hashes of important files like system executables should match the information given by the RPM database. Executables with erroneous hashes could be a sign of nefarious activity on the system.


Given output from the check command, identify the package that provides the output and reinstall it. The following trimmed example output shows a package that has failed verification, been identified, and been reinstalled:

$ rpm -Va --noconfig | awk '$1 ~ /..5/ && $2 != 'c''
S.5....T. /usr/bin/znew
$ sudo dnf provides /usr/bin/znew
gzip-1.10-8.el9.x86_64 : The GNU data compression program
$ sudo dnf reinstall gzip
$ rpm -Va --noconfig | awk '$1 ~ /..5/ && $2 != 'c''
[no output]
