The Known Beacons Attack (34th Chaos Communication Congress)
George Chatzisofroniou
The recent key reinstallation attacks (KRACK) against the WPA2 protocol revealed how an adversary can easily eavesdrop, and in some cases tamper, a Wi-Fi connection secured by the WPA2 protocol. At the same time, Wi-Fi automatic association attacks achieve a similar result (man-in-the-middle position) not by attacking...
Using SystemTap to determine the exploitability of unbound memory overflows
Nikolaos Naziridis
Hello, my name is Nikos Naziridis and I am a security researcher at CENSUS. In this post, I will present how SystemTap and kernel instrumentation in general, could be used to aid the process of determining the exploitability of unbound memory overflows and the detection of thread race condition bugs.
The Linux kernel memory allocators from an exploitation perspective
Patroklos Argyroudis
In anticipation of Dan Rosenberg's talk on exploiting the Linux kernel's SLOB memory allocator at the Infiltrate security conference and because I recently had a discussion with some friends about the different kernel memory allocators in Linux, I decided to write this quick introduction. I will present some of the...
Linux kernel SUNRPC off-by-two buffer overflow
Patroklos Argyroudis
An off‑by‑two stack buffer overflow in the Linux SUNRPC subsystem (kernel versions 2.6.32 through 2.6.32‑rc7) allows out‑of‑bounds writes in the function rpc_uaddr2sockaddr() when processing universal address strings of maximum length. Because the function writes two bytes past the end of a fixed‑size stack buffer, a...
