NVD Description

Note: Versions mentioned in the description apply only to the upstream sudo package and not the sudo package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

sudo 1.3.5 through 1.7.10 and 1.8.0 through 1.8.5, 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 connecting to the 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.
