(RHSA-2017:1381) Important: sudo security update

The sudo packages contain the sudo utility which allows system administrators to
provide certain users with the permission to execute privileged commands, which
are used for system management purposes, without having to log in as root.

Security Fix(es):

• A flaw was found in the way sudo parsed tty information from the process
  status file in the proc filesystem. A local user with privileges to execute
  commands via sudo could use this flaw to escalate their privileges to root.
