INITIAL RELEASE:    05 May 2004



POTENTIAL SECURITY IMPACT:    Remote Denial of Service (DoS)

SOURCE:    HEWLETT-PACKARD COMPANY
HP Software Security Response Team

REFERENCES:    CAN 2004-079, CAN-2004-0112

VULNERABILITY SUMMARY:

A potential security vulnerability has been identified with
Management Agents using OpenSSL and SSL/TLS which could be
exploited remotely to create a denial of service (DoS) in HP WBEM
Services on HP-UX and RedHat Enterprise Linux (RHEL).

SUPPORTED SOFTWARE VERSIONS*:  ONLY impacted versions are listed.

HP9000 Servers running HP-UX release B.11.00,  B.11.11 and
B.11.23 with versions of the following  products are affected:

- - HP WBEM Services for HP-UX, A.01.05.08 or earlier (B8465BA).
  Version A.01.05.08 of this product includes OpenSSL 0.9.6k.

- - HP WBEM Services for HP-UX, A.02.00.00 (B8465BA).
  This product includes OpenSSL 0.9.6k.

RedHat Enterprise Linux,  RHEL AS 2.1 with the following HP
product numbers/versions are affected:

- - HP WBEM Services for Linux, A.02.00.01

BACKGROUND:

The Common Vulnerabilities and Exposures project has identified
potential vulnerabilities in OpenSSL (CAN-2004-079,
CAN-2004-0112).

1. The do_change_cipher_spec function in OpenSSL allows remote
   attackers to cause a denial of service via a crafted SSL/TLS
   handshake that triggers a null dereference.
   http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0079

2. The SSL/TLS handshaking, when using Kerberos ciphersuites, does
   not properly check the length of Kerberos tickets during a
   handshake, which allows remote attackers to cause a denial of
   service via a crafted SSL/TLS handshake that causes an
   out-of-bounds read.
   http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0112

It affects the following HP product numbers/versions on HP-UX
releases B.11.00, B.11.11, and B.11.23:

 - HP WBEM Services for HP-UX, A.01.05.08 or earlier (B8465BA)

 - HP WBEM Services for HP-UX, A.02.00.00 (B8465BA)

It also affects the following HP product numbers/versions on
RHEL AS 2.1:

 - HP WBEM Services for Linux, A.02.00.01

AFFECTED VERSIONS

The following is a list of affected filesets or patches and fix
information.

On HP-UX, to determine if a system has an affected version,
search the output of "swlist -a revision -l fileset" for an
affected fileset or patch, then determine if a fixed  revision or
applicable patch is installed.

HP-UX B.11.00

HP-UX B.11.11

HP-UX B.11.23

============

WBEMServices.WBEM-CORE

HP WBEM Services

action: install revision A.01.05.09 or subsequent

WBEMServices.WBEM-CORE

HP WBEM Services

action: install revision A.02.00.02 or subsequent

END AFFECTED VERSIONS

On Linux, to determine if a system has an affected version, search
the output of "rpm -qa | grep wbem" for an affected fileset or
patch, then determine if a fixed revision or applicable patch is
installed.

hp.com-wbem-2.0.1-rhas2_1


RESOLUTION:

The OpenSSL group has released patches to fix the vulnerabilities
in OpenSSL 0.9.7d.  For customers using HP WBEM Services, HP has
incorporated  OpenSSL 0.9.7d in the following product:

- - HP WBEM Services for HP-UX, A.01.05.09 or later

- - HP WBEM Services for HP-UX, A.02.00.02 or later

- - HP WBEM Services for Linux, A.02.00.02 or later
