E0050: dsa.dat file shouldn't be globally writable

Product: Host Links 4.0.0, Gline
Platform: Any
Status: Closed, fixed in 4.0.1 and 4.1.0
Last updated: 1996-07-19 20:52:13

The dsa.dat file is the data file created from dsa.cfg by the glcc utility.
It is used by the DIWS and DSA line handlers. Because these need to
read/write from the file, it was created with global read/write access.

It was pointed out that this is a security problem. It allows any user
with UNIX shell access to edit the dsa.dat file and bypass security
restrictions therein or to just create problems for other users. It also
makes it impossible to put passwords into the dsa.cfg and set it
unreadable, as the compiled dsa.dat is still readable by everyone.


The dsa.dat file now inherits the permission setting of the dsa.cfg file.
By default this means read access for everyone and write access only for
the Host Links administrator. You may chmod dsa.cfg to something even
stricter, like no access at all for anyone but the administrator. The next
rerun of glcc will propagate the setting down to the dsa.dat file.
