CAN-2003-0618 leaks file existance information
Last modified: 2007-04-18 13:02:31 EDT
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.
# mkdir ~root/delme; chmod 700 ~root/delme;touch ~root/delme/1
$ 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 ...
Debian released an errata for this issue in Feb 2004.
Does this issue affect FC 1 as well?
The answer to my own question is yes. This still affects
Will we see a RHL 9 erratum before its EOL?
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.
