Kernel Root Exploit via a ptrace() and execve() Race Condition
Показать описание
Let's have a look at a recent kernel local privilege escalation exploit!
00:00 - Introduction
00:15 - Exploit PoC
00:39 - main()
00:52 - prepare_shellcode()
02:39 - mmap() shared memory to signal "ready" state
03:07 - fork() into [child] and [parent]
03:44 - [parent] wait for the child
04:00 - [child] unveil() loop
05:03 - [parent] ptrace ATTACH and POKE child
05:58 - [child] execve("passwd")
06:38 - [parent] PEEK entrypoint of child in loop
07:34 - [parent] child entrypoint changes!
07:49 - Exploit Walkthrough
09:20 - Root Shell via Shellcode
10:10 - Vulnerability Summary
10:37 - Which UNIX-like Kernel is this?
12:44 - The importance for Security Research
