It runs with the SUID bit set and may be exploited to access the file
system, escalate or maintain access with elevated privileges working as a
SUID backdoor. If it is used to run sh -p

shell to run with SUID privileges.
It runs in privileged context and may be used to access the file system,
escalate or maintain access with elevated privileges if enabled on sudo
