Behebungsmethode: Anleitung oder Infrastruktur-Patch

Perform the following: ; Capture the output of the previous audit command to a file named nonroot- files.txt and review any files not owned by root to ensure the files are necessary and are not expected run-time files. Delete any unnecessary files, and ensure any run-time files are being created in the appropriate run-time directory. # find $BIND_HOME -type f \! -user root | egrep -v \ \^$DYNDIR\|\^$SLAVEDIR\|\^$DATADIR\|\^$RUNDIR\|\^$LOGDIR\|\^$TMPDIR > \ $TMPDIR/nonroot-files.txt ; The remaining non-run-time files should be changed to be owned by root, with a command like the following: \# cat $TMPDIR/nonroot-files.txt | xargs chown root \# rm $TMPDIR/nonroot-files.txt
