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.

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 program.

You can download the program cow attack.c from the website of the lab. The program has three threads: the main thread, the write thread, and the madvise thread. The main thread maps /zzz to memory, finds · where the pattern "222222" is, and then creates two threads to exploit the Dirty COW race condition

March 16, 2022 - Run multiple dbt seed commands for the same table at the same time. A race condition is bound to occur.

This task is significantly more difficult, so if instructors do not want to include this task, they can make it optional. Shellcode Lab: There is no significant change. Environment Variable and Set-UID Lab: This is no significant change.

December 19, 2020 - I ran the vulp.c code snippet as below. Before I setuid on vulp, it can normally modify the tmpfile. However, after I setuid, it fails with a segmentation fault. I looked into the program and find that it passed the check of access but f...
