Workarounds and Mitigations
Until the fixes can be applied, a workaround is to remove the setuid from the files in the /usr/lpp/mmfs/bin directory. Determine the set of files with setuid bit by running
ls -l /usr/lpp/mmfs/bin | grep r-s
Then reset the setuid bit for each such file by issuing this command on each file
chmod u-s file
Once the workaround is applied, a number of commands may no longer work when not invoked by unprivileged users, including:
mmchfileset
mmcrsnapshot
mmdelsnapshot
mmdf
mmedquota
mmgetacl
mmlsdisk
mmlsfileset
mmlsfs
mmlsmgr
mmlspolicy
mmlspool
mmlsquota
mmlssnapshot
mmputacl
mmsnapdir
