Information

AlmaLinux OS 9 must be configured so that the cryptographic hashes of system files match vendor values.

GROUP ID: V-269292
RULE ID: SV-269292r1050174

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.

Solution

Given the 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, reinstalled, and then passed re-verification:

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

S.5....T. /usr/bin/tar

$ dnf whatprovides /usr/bin/tar

tar-2:1.34-6.el9_1.x86_64 : GNU file archiving program

$ dnf reinstall tar

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

[no output]
