Summary
The Qualys Security team discovered that sudo, a program designed to provide limited super user privileges to specific users, does not properly parse '/proc/[pid]/stat' to read the device number of the tty from field 7 (tty_nr). A sudoers user can take advantage of this flaw on an SELinux-enabled system to obtain full root privileges.
