All these apps will crash on receiving the malicious GIF. I haven’t test Twitter, but should you find a way to post the malformed GIF online (which I think can be done by manipulated the post stream to bypass the frontend filtering, but I was too busy to try that), the client should also crash as well. What make things worse is that many clients will automatically reload and reparse the image on open, triggering the vulnerability again and again, lead to infinite loop and eliminating the need for attacker to persistent – -b DEMO video1 The first video demonstrates receiving malformed gif file via iMessage lead to crash. The Journey of a complete OSX privilege escalation with a single vulnerability – Part 1 In previous blog posts Liang talked about the userspace privilege escalation vulnerability we found in WindowServer.
Now in following articles I will talk about the Blitzard kernel bug we used in this year’s pwn2own to escape the Safari renderer sandbox, existing in the blit operation of graphics pipeline. From a exploiter’s prospective we took advantage of an vector out-of-bound access which under carefully prepared memory situations will lead to write-anywhere-but-value-restricted to achieve both infoleak and RIP control. In this article we will introduce the exploitation methods we played with mainly in kalloc.48 and kalloc.4096. First we will first introduce the very function which the overflow occurs, what we can control and how these affect our following exploitation. This entry was posted in, on.
