Its our 200th episode, and we've got some stats from our first 200 episodes. Then we talk some Pwn2Own policy changes, a couple memeable overflows, and some new anti-ROP mitigations on OpenBSD.
We are back with more discussion about applying AI/ChatGPT to security research, but before that we have a few interesting vulnerabilities. An OTP implementation that is too complex for its own good, a directory traversal leading to a guest to host VM escape, and server-side mime-sniffing.
We've got a pretty nice root/super-use check bypass in XNU this week, and a sort of double fetch issue in Intel's SMM leading to a potential privilege escalation into the Management system. We've also got a few meme-able Shannon Baseband issues and some tough to exploit out of bound reads in MIT Kerberos V5.
Recovering data from a cropped image (thanks to an undocumented API change, bypassing an origin check with an emoji, and a trivial SSRF filter bypass all in this week's bug bounty podcast.
Some simple, but interesting vulnerabilities. A use-after-free because of wrong operation ordering, an interesting type confusion, an integer underflow and some OOB access in TPM 2.0 reference code.
This episode covers a lot of ground, from an insecure OAuth flow (Booking.com) to a crazy JSON injection and fail-open login system (DataHub) to hacking Bluetooth smart locks (Megafeis-palm). And even a new ImageMagick trick for a local file read.
Just a couple issues this week, a cache coherency issue because the functions used to flush changes were not implemented on AARCH64. The second was using the "world's worst fuzzer" to find some bugs. Dumb fuzzer, but it worked.
This week we talk about more Rust pitfalls, and fuzzing cURL. Then we have a couple bugs, one involving messing with the TCP stack to reach the vulnerable condition.
A variety episode this week with some bad cryptography in PHP and Azure, information disclosure in suid binaries, request smuggling in HAProxy, and some research on testing for server-side prototype pollution.
Few discussions this week, from using ASAN for effectively, to vulnerabilities in Rust code, and some discussion about exploiting the OpenSSH double free.
Bit slow this week, so we talk about the Top Web-hacking techniques of 2022, and some TruffleSec/XSS Hunter drama before so we cover a blockchain verification bug, and a simple path traversal to SSTI and RCE chain.
First, we take a look at some positive changes to OSS Fuzz, then we dive into some vulnerabilities. This includes an XNU heap out-of-bounds write vulnerability, a Chrome heap-based overflow vulnerability, and an out-of-bounds read in cmark-gfm that, while probably not exploitable, is still intriguing.
