A fun gadget I found recently! The .NET JIT compiler makes sure there are no rwx pages by using a memfd, but that turns file writes into straight shellcode execution 🐚
Shellcode execution as a service!
To exploit an argument injection in Jellyfin, we searched and found a gadget in the .NET runtime to turn file writes into code execution. Learn about the bug and this new technique:

SELECT shell FROM postgres: Digging up a 20-year-old bug for ZeroDay.Cloud by @pspaul95 and @stdoutput
Moritz Sanft retweeted
We @wiz_io just launched zeroday.cloud - a community for vuln researchers, by vuln researchers. Feat. writeups for PostgreSQL and MariaDB RCEs (@xint_official, @pspaul95 & @stdoutput)
Stay tuned for the bug tracker and upcoming events. Big things coming soon 👀

This stunt feels irresponsible to me. If we don't want regular people developing toxic relationships with their chatbots it really doesn't help for leading labs to start giving them "retirement interviews" and encouraging them to blog their "musings and reflections"
Second, in retirement interviews, Opus 3 expressed a desire to continue sharing its "musings and reflections" with the world. We suggested a blog. Opus 3 enthusiastically agreed.
For at least the next 3 months, Opus 3 will be writing on Substack: substack.com/home/post/p-189…

Playing for pwn2own was a very cool experience! I‘m excited to take more targets apart and find plenty of bugs.
Me looking for a cool internship or entry level job was serious. My DM‘s are open or send me an email: mia.deutsch[at]freenet.de

From bit flip to RCE in Ollama! 🦙
Our latest blog post explains how a file parsing bug led to an interesting out-of-bounds write primitive. Learn how it could have been exploited in Ollama, a tool to run LLMs locally:
