AUSCERT External Security Bulletin Redistribution
ESB-97.067 -- Hewlett-Packard Security Bulletin #00062
29 May 1997
===========================================================================
Hewlett-Packard has released the following security bulletin concerning
a vulnerability in VirtualVault A.01.01. The VirtualVault Transaction
Server product provides for secure data connections to CGI programs. If
the CGI program invoked does not completely read its input data, subsequent
CGI programs could receive a previous CGI's input data. This data
corruption could result in users requests being refused by the CGI, or
stale data being input (and visible) into the current CGI.
The following security bulletin is provided as a service to AUSCERT's
members. As AUSCERT did not write this document, AUSCERT has had no control
over its content. As such, the decision to use any or all of this
information is the responsibility of each user or organisation, and should
be done so in accordance with site policies and procedures.
Contact information for Hewlett-Packard is included in the Security
Bulletin below. If you have any questions or need further information,
please contact them directly.
If you believe that your system has been compromised, contact AUSCERT or
your representative in FIRST (Forum of Incident Response and Security Teams).

I. CGI Data Corruption
A. Nature of the problem
The VirtualVault Transaction Server product provides for secure
data connections to CGI programs. If the CGI program invoked does
not completely read its input data, subsequent CGI programs could
receive a previous CGI's input data. This data corruption could
result in users requests being refused by the CGI, or stale data
being input (and visible) into the current CGI.
B. Fixing the problem
The problem can be eliminated by applying a patch to your
installation.
C. Recommended Solution
Hewlett-Packard recommends that PHSS_10337 is applied to all
systems running VirtualVault Transaction Server Version A.01.01.
Note that this patch is not needed for versions A.01.00 or
A.02.00, as the problem does not exist in these versions.
