I've never felt one with any other movie character like this. RIP, legend!

@joxean Don't give them ideas please!

Public preview of synced passkeys brings the security benefits of MFA with simpler usability, while avoiding the security risks of weaker MFA options like SMS. However, even the simplest MFA can fail when credentials are lost, making account recovery a critical part of the user experience. To improve usability in such cases, we are introducing public preview for account recovery with AI-powered biometric match against government issued IDs across 192 countries.

@mumblegrepper I wouldn't be surprised if this was the actual strategy...

[CVE-2025-14282] dropbear: privilege escalation via unix domain socket forwardings

https://github.com/turistu/odds-n-ends/blob/main/CVE-2025-14282.md

It's 2025, and I have to prompt an LLM no less than 5 times to figure out how to add a new keyboard layout to Windows Server 2025, becase 1) the UI turned absolutely shit 2) the built-in search is optimized for ads instead of discovering functionality.

Also, Disk Management is gone, and you get no meaningful results for "disk" in the Start Menu. But when you *right click* the Start icon it's there. Why would it be so hard to make this discoverable by search (or leaving a shortcut with the original name)??

Rust is is not a "silver bullet" that can solve all security problems, but it sure helps out a lot and will cut out huge swatches of Linux kernel vulnerabilities as it gets used more widely in our codebase.

That being said, we just assigned our first CVE for some Rust code in the kernel: https://lore.kernel.org/all/2025121614-CVE-2025-68260-558d@gregkh/ where the offending issue just causes a crash, not the ability to take advantage of the memory corruption, a much better thing overall.

Note the other 159 kernel CVEs issued today for fixes in the C portion of the codebase, so as always, everyone should be upgrading to newer kernels to remain secure overall.

Apparently CVE-2025-59718 and CVE-2025-59719 are now EITW.

@fwaggle on my Ubuntu 22.0 and 24.0 the ed25519 host public key is not in PEM but in the <type> <key> format (no <comment> section).

What distro uses PEM? I can try to convert it to the type-format and see if the daemon blindly accepts it.

../ in FreshRSS. How did no one recommend that one to me yesterday? A new ../ would have been fun.

@jerry @Landsil @bagder My f2f's often divert to discussing AI so I think that already happened.

With H2HC on hiatus this year, the security community stepped up to create the 307 Temporary Security Conference—and we were proud to be part of it!

We presented our research on vulnerabilities in the CAN BCM protocol in the Linux kernel.

Thank you to everyone who watched!

The slides and exploit demos are now available.

Memory bugs, such as use-after-free and buffer overflows, are the most exploited vulnerability class; however, AddressSanitizer's 2-4x performance overhead makes it unusable in production.

So, we recommend GWP-ASan, which uses sampling and guard pages to detect memory safety bugs at scale. Learn the technique and how to implement it in your C++ projects using LLVM's scudo allocator:

I want things that are above my reading level, that's how I get better at reading 🤔😁
