Re: Moving ahead



REJECTED can mean "- it is unconfirmed (or not sufficiently
confirmed)"

I have searched many of the usual places, and have not been able to
find a dtappgather DOS attack.  Thus, I am concerned that we will be
unable to distinguish a new bug from this one.

I am familiar with two dtappgather bugs.  One is based on poor
permissions for /var/dt/appconfig/appmanager/ and
/var/dt/appconfig/appmanager/generic-display-0.  The other is based on 
poor checking of the DTUSERSESSION environment variable.  Both allow
the unauthorized chowning of a file to the user who invokes
dtappgather.

I can see using these as DOS attacks only insofar as root can damage
the local machine; these bug are promotion bug only as far as I see.

It may be that CERT has obfuscated the bug with the fact that, in
promotion, DOS attacks were happening.  Perhaps this was incompetent
script kiddies misuing an exploit script.

Does anyone have details of what actually led up to CA-98-02, so that
we can understand the bug?  Is it a matter of removing the DOS
references so that CAN-1999-0014 refers only to promotion?
