Vulnerability with OmniBack NT Clients - ------------------------------------------------------------------------- HEWLETT-PACKARD COMPANY SECURITY BULLETIN: #00115 31 May 2000 - ------------------------------------------------------------------------- The information in the following Security Bulletin should be acted upon as soon as possible. Hewlett-Packard Company will not be liable for any consequences to any customer resulting from customer's failure to fully implement instructions in this Security Bulletin as soon as possible. - ------------------------------------------------------------------------- PROBLEM: HP OpenView OmniBack II inet daemon causes memory leaks. PLATFORM: Windows NT 4.0 Systems running OmniBack Version 3.00 or 3.10. DAMAGE: Potential system crash caused by repeated remote access. SOLUTION: Apply the appropriate patch noted below. AVAILABILITY: The patch is currently available. - ------------------------------------------------------------------------- I. A. Background The OmniBack inet daemon running on an HP OpenView OmniBack II NT client does not release all used memory resources after it has closed a remote connection. If such a client system is contacted repeatedly and very often through the OmniBack port number, it can run out of system resources and crash. B. Fixing the problem This problem can be eliminated by installing the appropriate patch on the OmniBack NT Installation Server and then distributing the patched binaries to the OmniBack NT clients using the client upgrade action in the OmniBack Manager GUI. OMNIBACK_00011 for HP OpenView OmniBack version 3.00, or OMNIBACK_00012 for HP OpenView OmniBack version 3.10.
