Description Mark J. Cox 2004-02-04 16:35:16 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: 9

Debian released an errata for this issue in Feb 2004.

Comment 1 Leonard den Ottolander 2004-04-21 15:52:07 UTC
Does this issue affect FC 1 as well?


Comment 2 Leonard den Ottolander 2004-04-21 17:12:09 UTC
The answer to my own question is yes. This still affects
perl-suidperl-5.8.3-16.

Will we see a RHL 9 erratum before its EOL?


Comment 3 Mark J. Cox 2004-04-22 15:37:22 UTC
Discussion over the proposed patch reached the conclusion that the
patch wasn't the right one to solve this issue without side-effects. 
In fact Debian recently reissued their packages with an altered fix. 
Given the low risk of this issue I feel it unlikely that we will
errata this for RHL9.
