Strumpf Noir Society Advisories
! Public release !
-= Denicomp REXECD/RSHD Denial of Service Vulnerability =-
Release date: Thursday, May 3, 2001
Denicomp's REXECD and RSHD products are ports of their counterparts
on Unix-based systems, allowing the use of the rcp, rsh and rexec
commands on machines running MS Windows.
These products can be obtained through the vendors website at:
There exists a problem in the port-handling code of mentioned
products which exposes the services provided by these to a DoS attack.
When a string of +/- 4300 bytes is sent to the listening port of
the REXEC and/or RSH daemons (defaulting to the standard 512 and
514 ports), the service in question will die.
A restart will be needed to regain full functionality.
Vendor has been notified and has verified this problem. New versions
of these products will be released from the vendor's website shortly.
