Amazon Linux AMI : sudo (ALAS-2017-843)

medium Nessus Plugin ID 100644


The remote Amazon Linux AMI host is missing a security update.


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.



Run 'yum update sudo' to update your system.
