Serious problem after tetex security update

[Andreas Goesele <Goesele@hfph.mwn.de>]

Hi!

After the last security update with libkpathsea3 and tetex-bin my
LaTeX installation doesn't work any more. When I try to compile a
LaTeX file I get:

I can't find the format file `latex.fmt'!

What can I do to get a working LaTeX installation back? I urgently
need it!

Thanks a lot in advance!
