o Security Bulletin Digest Split
------------------------------
The security bulletins digest has been split into multiple digests
based on the operating system (HP-UX, MPE/iX, and HP Secure OS
Software for Linux). You will continue to receive all security
bulletin digests unless you choose to update your subscriptions.
To update your subscriptions, use your browser to access the
IT Resource Center on the World Wide Web at:
http://www.itresourcecenter.hp.com/

TEXT
-----------------------------------------------------------------
HEWLETT-PACKARD COMPANY SECURITY BULLETIN: HPSBUX0208-217
Originally issued: 11 Sept 2002
SSRT 2310 OpenSSL Vulnerabilities
-----------------------------------------------------------------
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: A remotely exploitable potential vulnerability in a
Apache OpenSSL code.
PLATFORM: HP9000 Servers running HP-UX release 11.00, 11.11, 11.20,
and 11.22 with versions 1.3.26.04 or 2.0.39.04 and earlier,
of the HP Apache product installed are affected.
DAMAGE: Potential for increased privilege, DoS, or execution of
arbitrary code.
SOLUTION: For HP-UX releases 11.00, 11.11, 11.20 and 11.22 as well
as release 11.11 running IPv6, download new product
bundles for OpenSSL 0.9.6g (PA and IPF) from
<www.software.hp.com>.
MANUAL ACTIONS: Yes - Install repaired binary.
AVAILABILITY: Complete product bundles are available now on
<www.software.hp.com>
------------------------------------------------------------------
A. Background
The CERT Advisory CA-2002-23 regarding Multiple Vulnerabilities
In OpenSSL, affects the following HP product numbers:
B9415AA Apache 1.3.x HP-UX releases 11.00 and 11.11
B9416AA Apache 2.x HP-UX releases 11.00 and 11.11
B9415AA Apache 1.3.x HP-UX releases 11.20 and 11.22
B9416AA Apache 2.x HP-UX releases 11.20 and 11.22
B9416BA Apache 2.x IPv6 HP-UX release 11.11
With this release HP has upgraded to OpenSSL 0.9.6g, and fixes
certain known OpenSSL vulnerabilities.
See CVE issues: CAN-2002-0656, CAN-2002-0657,CAN-2002-0655
at <http://cve.mitre.org/>.
More information can be found at <http://www.openssl.org>.
The OpenSSL community has released OpenSSL 0.9.6g as the best
known version superseding the OpenSSL 0.9.6e release that was
identified in the CVE report.
The defects in mod_ssl version 2.8.10 (Apache 1.3.x only) is also
addressed herein.
Finally, this release also has upgraded MM version 1.2.1, which
fixes certain known vulnerabilities. OSSP mm library (libmm)
before 1.2.0 allows the local Apache user to gain privileges.
More details can be found in the issue CAN-2002-0658 at
<http://cve.mitre.org/>. (Apache 1.3.x only)
Before updating, make sure to stop any previous HP Apache binary.
Otherwise, the previous binary will continue running, preventing
the new one from automatically starting, although the
installation would be successful.
The command to stop the HP Apache binary is:
for 1.3.26:
/opt/apache/bin/apachectl stop
for 2.0.39:
/opt/hpapache2/bin/apachectl stop
HP Apache automatically starts upon installation if port 80
is available.
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.
