- Relocation of w00w00.org
-
- After being relocated, http://www.w00w00.org is up and running. Although
- we are using an old backup of the site (off the mirror), we have added
- a new w00bio and w00giving (advisories) section. When we receive the
- newest backup of the site, we'll finish updating (notice all the new
- w00quotes!). You find our bio, articles, code/projects, and advisories
- on the site. Thanks
-
- Note on w00w00
-
- At 30+ active members (in seven countries, three continents, and twelve
- US states), w00w00 has grown into the world's largest non-profit security
- team. Of course, we love our nearest competitors, Cult of the Dead Cow
- (CDC), at 22-23 members. [The largest for-profit security team that I
- (the author) am aware of is ISS's X-Force.]

-
- When you apply patches to binaries (i.e., for bug fixes), the original,
- unpatched binary files (with the suid/sgid bits maintained) are stored
- in /var/sadm. By default, the permissions on this directory is 755.
- This allows normal users to execute and exploit old binaries leftover
- from patching.
-
- ---------------------------------------------------------------------------
- Patch:
-
- Run 'chmod o-x /var/sadm' to remove execution privileges for normal
- users.
