Ubuntu 11.04 and 12.04 come with an built-in protection against race condition attacks. This scheme works by restricting who can follow a symlink. According to the documentation, "symlinks in world-writable sticky directories (e.g. /tmp) cannot be followed if the follower and directory owner do not match the symlink owner." In this lab, we need to disable this protection.

Race Condition Vulnerability Lab Solution
• OverviewThe learning objective of this lab is for students to gain the first-hand experience on the race-condition vul-nerability by putting what they have learned about the vulnerability from class into actions. A race condition occurs when multiple processes access and manipulate the same data concurrently, and the outcome of the execution depends on the particular order in which the access takes place. If a privileged program has a race-condition vulnerability, attackers can run a parallel process to “race” against the privileged program, with an intention to change the behaviors of the p
