The blog post is the full version of my talk at 38c3. It's about some vulnerabilities we found in libarchive and some interesting behaviors of libarchive that you don't want to miss. My favorite part is it only took us 56 seconds to trigger a crash by AFL++.
Our latest deep dive explores libarchive vulnerabilities under recent Windows 11 updates. ππ Check out NiNi's (@terrynini38514) technical write-up for key insights and security implications. Read more here: https://t.co/MUb7koMIrw
