Description

sudo before 1.7.10p5 and 1.8.x before 1.8.6p6, when the tty_tickets option is enabled, does not properly validate the controlling terminal device, which allows local users with sudo permissions to hijack the authorization of another terminal via vectors related to a session without a controlling terminal device and connecting to a standard input, output, and error file descriptors of another terminal. NOTE: this is one of three closely-related vulnerabilities that were originally assigned CVE-2013-1776, but they have been SPLIT because of different affected versions.
