New files in setuid.today

[Andrew Robinson]

Hi everyone,

I have some new file names in my /var/log/setuid.today file.  There
are things on an external drive, pdfs, html documents, etc.  The only
common factor that I can see is that all of them are 's' in the group
permissions.  An example is:

1766558 -rw-r-sr--  1 andrewr  andrewr     8076 Jul 24 19:38:17 2005
/home/andrewr/0.svn/0.infrastructure/www_public/andrewpr.JPG

Just checking the names of the files, I know what each one of them is
(or is supposed to be!) and none of them are supposed to bne
executable.

Can anyone tell me how this might happen, and what I should do to
clean it up?  

Thanks!

Andrew
