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.
