Dead Fred Diggler, You are not as much of an expert as you may have thought. Any foolish teenager can break software, but it takes a computer science degree to design software. For example, I have found a design flaw vulnerability (DFV) in your exploit. By passing a specially crafted argument to the program, an attacker can execute arbitrary code with Diggler privileges. I have also uncovered several race conditions. If one executes the command 'pkill -11' on the program, for example, memory corruption seems to occur, and most modern operating systems output the buffer overflow code: Segmentation fault I hope you consult with experts before being so hasty to post your attempt at a technical rant. LOLOL. J On Thu, 13 Dec 2007 23:20:21 -0500 Fredrick Diggle <fdiggle () gmail com> wrote:
You should post this to milw0rm as it can always use quality exploit code like this. I also have some priv8 code which I would like to disclose which is the same type of vulnerability. /* * Author: Fredrick Diggle * Vuln: execve system call allows arbitrary code execution * Status: VERY PRIV8 * DO NOT RELEASE OR FRED DIGGLE WILL EAT YOUR FAMILY */ #include <stdlib.h> #include <stdio.h> #include <unistd.h> #define INFINITY 73 #ifdef DIGGLEISAWESOME int main(int argc, char **argv) { if (argc < 2) { fprintf(stderr, "usage: %s [command to run]\n\tPRIV8 Fred Diggle 0day\n", argv[0]); return INFINITY; } execve(argv[1], &argv[1], 0); } #endif On Dec 13, 2007 8:57 PM, kcope <kingcope () gmx net> wrote:exploiting "features" (see attached) - -kcope / 2007 -- Psssst!
