SSRT3614 - HP OpenCall Multiservice Controller (OCMC)
DoS (Denial of Service)


-----------------------------------------------------------------
NOTICE:
There are no restrictions for distribution of this Bulletin
provided that it remains complete and intact.

The information in this Security bulletin should be acted upon as
soon as possible.

INITIAL RELEASE:
25 March 2004



POTENTIAL SECURITY IMPACT:
Remote Denial of Service (DoS)

SOURCE: HEWLETT-PACKARD COMPANY
HP Software Security Response Team

REFERENCES: CERT CA-2004-01,CISCO Advisory 47843

VULNERABILITY SUMMARY:

A potential security vulnerability has been identified in the
HP OpenCall MultiService Controller (OCMC) H.323 stack that may
allow a remote user to create a Denial of Service (DoS).




SUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed.

All versions HP OCMC v1.2 and HP OCMC v1.1 for HP-UX 11.0



BACKGROUND:
The HP Software Security Response team has contacted
the source and various other vendors and is not aware
of any malicious exploitation of any of the vulnerabilities
described in this bulletin.

A test suite developed by the U.K. National Infrastructure
Security Co-ordination Centre (NISCC) and the University of Oulu
Security Programming Group (OUSPG) has exposed vulnerabilities in
several implementations of the H.323 protocol.

The potential vulnerabilities may be exploited to produce a denial
of service (DoS) attack. Such an attack may cause an affected
product to failover or crash and failover. Due to its robust
design OCMC will recover from most attack scenarios. In the event
that OCMC does not recover, the attack can be stopped by blocking
the offending IP address. Attacks may also be blocked by
creating an access list to restrict TCP port 1720 traffic to
known, trusted IP addresses.

RESOLUTION:



HP will be providing patches to the impacted versions of OCMC:

OCMC v1.2 released January 2004
OCMC v1.1 patch 46
OCMC v1.1 patch 37

This bulletin will be revised as the patches become available
and patches will be available from the normal HP Services
support channel.
