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 attSecurity Vulnerabilities in OpenSSLackers 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: - hp-ux apache-based web server, v.1.0.03.01 or later (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 http://www.software.hp.com/ 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 C.

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. For information on the Security Patch Check tool, see: http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/cgi/ displayProductInfo.pl?productNumber=B6834AA The security patch matrix is also available via anonymous ftp: ftp://ftp.itrc.hp.com/export/patches/hp-ux_patch_matrix/ On the "Support Information Digest Main" page: click on the "HP Security Bulletin Archive".
