(HP Issues Fix for HP WBEM Services) OpenSSL SSL/TLS Handshade Flaws May Let Remote Users Crash OpenSSL-based Applications
SecurityTracker Alert ID:  1010082
SecurityTracker URL:  http://securitytracker.com/id/1010082
CVE Reference:   CVE-2004-0079, CVE-2004-0112   (Links to External Site)
Date:  May 6 2004
Impact:   Denial of service via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): A.01.05.08 or earlier (B8465BA), A.02.00.00 (B8465BA), A.02.00.01
Description:   Some vulnerabilities were reported in OpenSSL, primarily involving the processing of SSL/TLS protocol handshakes. A remote user can cause OpenSSL to crash. HP's WBEM Services are affected.

It is reported that there is a null-pointer assignment in the do_change_cipher_spec() function [CVE: CVE-2004-0079]. A remote user can perform a specially crafted SSL/TLS handshake with a target server to cause OpenSSL to crash on the target system. This may cause the application using OpenSSL to crash.

All versions of OpenSSL from 0.9.6c to 0.9.6k inclusive and from 0.9.7a to 0.9.7c inclusive are reportedly vulnerable to this null-pointer bug.

It is also reported that there is a flaw in performing SSL/TLS handshakes using Kerberos ciphersuites [CVE: CVE-2004-0112]. A remote user can perform a specially crafted SSL/TLS handshake against a server that is using Kerberos ciphersuites to cause OpenSSL to crash on the target system.

OpenSSL versions 0.9.7a, 0.9.7b, and 0.9.7c are reported to be vulnerable to this Kerberos handshake bug.

It is also reported that a remote user may be able to cause OpenSSL to enter an infinite loop due to a flaw in a patch introduced in 0.9.6d [CVE: CVE-2004-0081].

The vendor credits Dr. Stephen Henson of the OpenSSL core team as well as Codenomicon for supplying their TLS Test Tool and Joe Orton of Red Hat for performing the majority of the testing.

Impact:   A remote user can cause OpenSSL to crash, which may cause an application using OpenSSL to crash. The specific impact depends on the application that uses the OpenSSL library.
Solution:   HP has issued the following fixed versions:

- 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

SSRT4717 rev.0 Management Agents: remote DoS with OpenSSL SSL/TLS in HP WBEM Services

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:   	

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
