    If you’re tired of hearing about crypto32, elliptic curves, and other CVE-2020-0601 shenanigans, have a read over our new blog post on Windows’ Intel CET implementation in the face of SetThreadContext and NtContinue. Come for the exploit mitigation, stay for the XState Internals.

    I was reminded today of how darned well Windows handles relocations and Address Space Layout Randomization. Relocations are 2 bytes each (24 bytes each for Linux) and relocated pages are shared (not shared on Linux). So, ASLR is almost free on Windows, which is good for security

    With issues during some disclosures, Intel took our concerns *very* seriously and improved the communication and handling of issues *substantially* over the past year. This deserves recognition and I want to thank Intel for improving the process.
