Description of problem:
/etc/csh.cshrc has a logic error in the setting of umask in Red Hat 9.
 The line in error is

[ "`id -gn`" = "`id -un`" -a `id -u` -gt 99 ]

and should be 

if ( "`id -gn`" == "`id -un`" && `id -u` > 99 ) then

The bad line sets umask = 002 instead of 007.  It looks like bash that
was not fully converted to csh

Version-Release number of selected component (if applicable):
setup-2.5.25-1

How reproducible:
Always

Steps to Reproduce:
1.copy if statement to a file (fn)
2.place "echo" before the then and else clauses so the path taken is
printed
3.run csh fn     where fn is the name of the file
4. Observe the error
5. Also, just create a file by any means and examine it with (ls
-alt), observe that world read permissions are set.
    

Actual Results:  Error causes all files created by a user to have
world read permission set (umask 002)

Expected Results:  Files created by a user should have no world
permissions (umask 007)

Additional info:

To fix, replace the line
[ "`id -gn`" = "`id -un`" -a `id -u` -gt 99 ]
with
if ( "`id -gn`" == "`id -un`" && `id -u` > 99 ) then

The error can be a security issue as it exposes all user information
to any other user.
