Check Text ( C-27549r1_chk )
If /etc/shells exists, check the permissions 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 the permissions include a "+", the file has an extended ACL, this is a finding.

Fix Text (F-23721r1_fix)
Remove the extended ACL from the file. # chmod A- [shell]
