That'll surely be an interesting read for > whoever wants to look a bit at the details of how the Hurd works. And of > course thanks for finding and fixing the vulnerabilities :) Seconded. It=E2=80=99s interesting both from a security perspective and as= a deep dive into Mach/Hurd internals; excellent work, Sergey! Am I right that the fixes have not been applied yet in the upstream repository? Thanks, Ludo=E2=80=99.
