Description Leonard den Ottolander 2004-04-21 17:11:23 UTC

CAN-2003-0618 was reported 2003Jul29 to Debian. You can test for the
existance of files even if you don't have permission to do so by using
the suidperl command.

        $ su
        # mkdir ~root/delme; chmod 700 ~root/delme;touch ~root/delme/1
        # exit
        $ suidperl ~root/delme/1
        Script is not setuid/setgid in suidperl
        $ suidperl ~root/delme/2
        Can't open perl script "/root/delme/2": No such file ...

        Affects: Fedora Core 1, perl-suidperl-5.8.3-16

Debian released an errata for this issue in Feb 2004.

Comment 1 Leonard den Ottolander 2004-08-10 16:23:38 UTC

I should have tested this before submitting...

Getting "Permission denied"s. So there's no problem.
