CVE-2013-2776 Information

Description

sudo 1.3.5 through 1.7.10p5 and 1.8.0 through 1.8.6p6 when running on systems without /proc or the sysctl function with the tty_tickets option 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.
