CVE-2013-2777: Medium severity apple ios and macos vulnerability
sudo before 1.7.10p5 and 1.8.x before 1.8.6p6, when the ttytickets 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 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.
