Updated:    2018-05-08 [TLP:WHITE] Public disclosure


Affected software and risk
==========================

MODERATE risk vulnerability concerning DPM SRM Buffer Overflow

Package : DPM
CVE ID  : N/A

A buffer overflow vulnerability has been found in DPM SRM which allows an authorized user with a client host name longer 
than 63 characters to crash the DPM SRM.  It has been inadvertently triggered at a few sites by a legitimate user.

Actions required/recommended
============================

Sites are recommended to update their DPM servers as soon as possible, to ensure the service remains available. 


Affected software details
=========================

This is fixed as of DPM version 1.9.2.

All versions of the DPM server prior to this version are vulnerable. 

More information
================

Investigations into this vulnerability have not shown any exploit more serious than DoS, and nothing that can lead 
to access to the DPM host or exposure of data. 

However, it might be very easy to trigger this vulnerability, typically inadvertently. Hence we are keeping this 
advisory as 'AMBER' to allow sites to patch before it is exposed publicly. 

**Update 2018-05-08 Advisory made public**


Component installation information
