I gave Claude 3 the entire source of a small C GIF decoding library I found on GitHub, and asked it to write me a Python function to generate random GIFs that exercised the parser. Its GIF generator got 92% line coverage in the decoder and found 4 memory safety bugs and one hang.
Bought a prison laptop on eBay. Thought it should be just some generic laptop with a clear shell, turns out it's actually a bit more than that.
Security vulnerability in... qsort. Yes, the glibc's sort algorithm. It's all over the place on systems running the Internet. "All versions from at least September 1992 are affected". That makes it a more 32 years old bug. openwall.com/lists/oss-secu…

We found a critical vulnerability in #Putty SSH client with NIST P-521 keys, that allows private key recovery from only 60 signatures, CVE-2024-31497! If you use #Putty or #Filezilla with ECDSA P-521, upgrade now and generate a new key! Joint work with @TrueSkrillor, details ⬇️
Figured out how to feel better about my awful code. I just put all of my bad hacks at the bottom of a file, and give it a cute little house to live in, forever. Now I feel great.
this paper was sent out of anger to unsubscribe from a low-quality research journal's mailing list but ended up getting accepted
1. KASLR for an attacker with arbitrary local unpriv execution is not effective. 2, KASLR for heap based exploitation is not effective including remote attacks. 3. I believe this to be independent the details of KASLR implementation, OS and CPU for general compute systems.
As it was discovered and made public, I can finally say I had this universal KASLR bypass since 2020, and I patiently saw many discussions about the effectiveness of KASLR. I said nothing, not only because it was still a 0day, but because it's interesting to see how people are so…

Jia Tan's git commit to turn off Landlock sandboxing one week after Lasse Collin improved it. I understand the sandbox is for xz, the command line tool, and Jia did not need to disable it for the SSHD backdoor. 🤔The xz command also activates the backdoor?
Microsoft engineer: 500ms lag in liblzma? Something's up. Also Microsoft engineer: 45 minute lag in Microsoft Teams? Perfect.
Random math request: Given that >90% of CPUs are little endian - how much CO2 could we (very very very roughly) save if we switched network protocols to use little endian instead of big endian?
C++23 has "first-class UB": you, the language user, can make promises and let the program enter UB if you break them. int f(int x, int y) { [[assume(x == 27)]]; [[assume(x == y)]]; return y + 1; // May be optimised to `return 28`. }
In this post I'll use CVE-2023-6241, a vulnerability in the Arm Mali GPU that I reported last November to gain arbitrary kernel code execution from an untrusted app on a Pixel 8 with MTE enabled. github.blog/2024-03-18-gai…
