Juniper NSM remote Denial Of Service

"NetScreen-Security Manager is a software that enables you to integrate and
centralize management of your Juniper Networks NetScreen security environment."

More information can be found on
http://www.juniper.net/customers/support/products/nsm.jsp

Description:

Malicious user can cause a remote denial of service on
guiSrv(port 7800) and devSrv(port 7801) by sending specially
crafted and long strings.

NSM 2004 FP2 and FP3 are known to be vulnerable.

By default, a watchdog service is installed with NSM.
It is able to restart automatically dead services
(the test is about every 5 min).

Proof of Concept:

I am not intent to publicly disclose the PoC.

Workaround:

Upgrade at least to NSM FP4r1 also known as 2005.1

Thanks to quick responses from Juniper Security Team.
