Two Remote Holes in 10 Years
Just a quick note: Upgrade your OpenBSD installations as soon as possible as OpenBSD just had its second remote hole in ten years. While this doubles the number of remote holes found in OpenBSD, two is still a pretty low number. Details are on Undeadly and in Theo de Raadt’s post on misc@openbsd.org.
Westcoast Wrap-Up
In case anybody wonders, this is what I have done during my stay at the US westcoast.
- I gave four talks in total on Pyrex/SageX, commutative algebra implementations, and algebraic attacks against block ciphers.
- I got started on linking against Singular from SAGE. I am far from being finished but I am planning to put out a pre-alpha-poke-an-eye-out release soon.
- I got started on incorporating Gregory Bard’s M4RI implementation in SAGE and optimized it a little. Going to be released soon.
- I wrote a thread manager which might under some highly unlikely circumstances end up in FLINT. The point of a thread manager is to make sure the overhead of creating a new thread is minimized.
- co-worked on “fast integer” creation in SAGE. That means diving into Python and GMP internals to make the creation of new Integer objects fast.
- I helped a little on the IML and LinBox integration in SAGE.
- I wrote a SymbolicData wrapper for SAGE.
- I was a conference co-organizer for the first time.
