SSRT3499 SSRT3518 Security Vulnerabilities in OpenSSL
-----------------------------------------------------------------
NOTICE: There are no restrictions for distribution of this
Bulletin provided that it remains complete and intact.
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:
1. OpenSSL does not use RSA blinding by default, which allows
local and remote attackers to obtain the server's private
key by determining factors using timing differences on (1)
the number of extra reductions during Montgomery reduction,
and (2) the use of different integer multiplication
algorithms.
More details are available at:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0147
The problem has been fixed by enabling the blinding flag for
the RSA crypto algothrithms in HP-UX implementations.
2. The SSL and TLS components for OpenSSL 0.9.6i and earlier,
allow remote attackers to perform an unauthorized RSA private
key operation via a modified Bleichenbacher attack. This
attack uses a large number of SSL or TLS connections using
PKCS #1 v1.5 padding that causes OpenSSL to leak information.
More details are available at:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0131
IMPACT: Potential information leak.
** REVISED 01 **
PLATFORM: HP9000 Servers running HP-UX release 11.00, 11.11 and
11.22 with versions of the following products are
affected, and represented as:
product-name, version (product-tag/bundle-tag)
---> - hp apache-based web server, 1.3.27.01 or earlier
---> (ApacheStrong/B9415AA)
---> This product includes OpenSSL 0.9.6i
- hp apache-based web server, 2.0.43.04 or earlier
(HPApache/B9416AA, HPApache/B9416BA)
This product includes OpenSSL 0.9.6g
- hp-ux apache-based web server, v.1.0.02.01 or earlier
(hpuxwsAPACHE/hpuxwsApache)
This product includes OpenSSL 0.9.6i.
** REVISED 01 **
SOLUTION: For HP-UX releases 11.00, 11.11 and 11.22 download new
HP Apache product from http://www.software.hp.com/:
---> For ApacheStrong/B9415AA download the following:
---> - hp apache-based web server, 1.3.27.02
---> (ApacheStrong/B9415AA)
---> This product includes OpenSSL 0.9.6i (with patches)
---> http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/
---> cgi/displayProductInfo.pl?productNumber=B9415AA132702
For HPApache/B9416AA, HPApache/B9416BA and
hpuxwsAPACHE/hpuxwsApache download the following:

(hpuxwsAPACHE/hpuxwsApache)
This product includes OpenSSL 0.9.6i (with patches)
http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/
cgi/displayProductInfo.pl?productNumber=HPUXWSSUITE
NOTE: No IPv6 solution is available at this time. This Security
Bulletin will be updated when such becomes available.
MANUAL ACTIONS: Yes - Update
Install the product containing the fix.
For customers with HPApache/B9416AA or
HPApache/B9416BA installed, the fix requires
migration to hpuxwsAPACHE/hpuxwsApache and
removing the affected products from the system.
AVAILABILITY: Complete product bundles are available now on

CHANGE SUMMARY: Rev. 01 Added apache-based web server, 1.3.27.02
-----------------------------------------------------------------
** REVISED 01 **
A. Background
The Common Vulnerabilities and Exposures project
<http://cve.mitre.org/> has identified multiple potential
vulnerabilities in the OpenSSL (CAN-2003-0131, CAN-2003-0147).
It affects the following HP product numbers/versions on HP-UX
releases 11.00, 11.11 and 11.22:
---> - hp apache-based web server, 1.3.27.01 or earlier
---> (ApacheStrong/B9415AA)
- hp apache-based web server, 2.0.43.04 or earlier
(HPApache/B9416AA, HPApache/B9416BA)
- hp-ux apache-based web server, v.1.0.02.01 or earlier
(hpuxwsAPACHE/hpuxwsApache)
B. Recommended solution
The OpenSSL Group has released different patches to
OpenSSL 0.9.6i to fix the problems identified in the above
mentioned issues.
** REVISED 01 **
For customers using ApacheStrong/B9415AA, HP has incorporated
OpenSSL 0.9.6i (with patches) in the following product:
- B9415AA: hp apache-based web server 1.3.27.02
For customers using HPApache/B9416AA, HPApache/B9416BA and
hpuxwsAPACHE/hpuxwsApache, HP has incorporated OpenSSL 0.9.6i
(with patches) in the following product:
- hp-ux apache-based web server v.1.0.03.01 or later
http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/cgi/
displayProductInfo.pl?productNumber=HPUXWSSUITE
NOTE: No IPv6 solution is available at this time. This
Security Bulletin will be updated when such becomes
available.
** REVISED 01 **
Check for Apache Installation
-----------------------------
To determine if the Apache web server from HP is installed on
your system, use Software Distributor's swlist command. All
three versions products may co-exist on a single system.
For example, the results of the command
swlist -l product | grep -i apache
--> ApacheStrong 1.3.27.01 HP Apache-based Web Server
--> with Strong (128bit) Encryption
HPApache 2.0.39.01.02 HP Apache-based Web Server
hpuxwsAPACHE A.1.0.02.01 HP-UX Apache-based Web Server
Stop Apache
-----------------------------
Before updating, make sure to stop any previous Apache binary.
Otherwise, the previous binary will continue running,
preventing the new one from starting, although the installation
would be successful.
After determining which Apache is installed, stop Apache with
the following commands:
--> for ApacheStrong: /opt/apache/bin/apachectl stop
for HPApache: /opt/hpapache2/bin/apachectl stop
for hpuxwsAPACHE: /opt/hpws/apache/bin/apachectl stop
Download and Install Apache
-----------------------------
- Download Apache from Software Depot using the previously
mentioned links.
- Verify successful download by comparing the cksum with the
value specified on the installation web page.
- Use SD to swinstall the depot.
- For customers with HPApache/B9416AA or HPApache/B9416BA
installed, migrate to hpuxwsAPACHE/hpuxwsApache and
remove the affected products from the system.
Installation of this new version of HP Apache over an existing
HP Apache installation is supported, while installation over a
non-HP Apache is NOT supported.
Removing Apache Installation
----------------------------
If you rather remove Apache from your system than install a
newer version to resolve the security problem, use both
Software Distributor's "swremove" command and also "rm -rf"
the home location as specified in the rc.config.d file "HOME"
variables.
To find the files containing HOME variables in the
/etc/rc.config.d directory:
%ls /etc/rc.config.d | grep apache
apacheconf
hpapache2conf
hpws_apacheconf

To -gain access- to the Security Patch Matrix, select
the link for "The Security Bulletins Archive". (near the
bottom of the page) Once in the archive the third link is
to the current Security Patch Matrix. Updated daily, this
matrix categorizes security patches by platform/OS release,
and by bulletin topic. Security Patch Check completely
automates the process of reviewing the patch matrix for
11.XX systems. Please note that installing the patches
listed in the Security Patch Matrix will completely
implement a security bulletin _only_ if the MANUAL ACTIONS
field specifies "No."
The Security Patch Check tool can verify that a security
bulletin has been implemented on HP-UX 11.XX systems providing
that the fix is completely implemented in a patch with no
manual actions required. The Security Patch Check tool cannot
verify fixes implemented via a product upgrade.
