NVD - CVE-2013-2776

CVE-2013-2776 Detail

Modified

This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.

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.
