Check Text ( C-29858r488669_chk )
If /etc/shells exists, check the group ownership of each shell referenced. # cat /etc/shells | xargs -n1 ls -lL Otherwise, check any shells found on the system. # find / -name "*sh" | xargs -n1 ls -lL If a shell has a mode more permissive than 0755, this is a finding.

Fix Text (F-29846r488670_fix)
Change the mode of the shell. # chmod 0755
