Re: W32/Sobig-F - Halflife correlation ???

Realistically, it doesn't need a hole to communicate. All it needs to do
is impersonate a player that doesn't mind dying alot. It can still
with it's "team-mates" using the built-in communications channels in the
and it can still use CS servers as a directory service. These are FEATURES
of the game with no vulnerability required.

Regarding the half life exploits, the 'remote root' exploits have been
addressed to VALVe and they were fixed in 188.8.131.52d for linux (184.108.40.206d
for win32).. which was released July 30th 2003.
Now, the bug was reported to VALVe on April 18th 2003, but it didnt hit
bugtraq until July 29th, 2003.
On the other hand though, alot of server admins(from what I can grasp from
the hlds_linux mailing list) do not run x.1.1.1d for the simple fact that
it uses a bit more CPU then x.1.1.0c. There is an unoffical patch for
x.1.1.0c that does plug the hole.
Unless this worms communicating with an unknown hole or something...
