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/
Under the Maintenance and Support Menu, click on the "more..." link.
Then use the 'login' link at the left side of the screen to login

Under the notifications section (near the bottom of the page), select
Support Information Digests.
To subscribe or unsubscribe to a specific security bulletin digest,
select or unselect the checkbox beside it. Then click the
"Update Subscriptions" button at the bottom of the page.
o IT Resource Center World Wide Web Service

-----------------------------------------------------------------
HEWLETT-PACKARD COMPANY SECURITY BULLETIN: HPSBUX0209-215
Originally issued: 09 September 2002
SSRT2336 Security Vulnerability in XDR library
-----------------------------------------------------------------
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: Potential buffer overflow in XDR library.
PLATFORM: HP 9000 Series 700 and 800 10.20, 11.00, 11.11, and 11.22
DAMAGE: Potential unauthorized access, denial of service.
SOLUTION: Until patches are available manually install the
appropriate fixed libraries.
MANUAL ACTIONS: Yes - NonUpdate
Install the appropriate fixed libraries.
Relink any archived programs that call
xdr_array().
AVAILABILITY: This bulletin will be updated when patches are
available.
------------------------------------------------------------------
A. Background
CERT Advisory CA-2002-25 reports an integer overflow in
certain implementations of XDR libraries. Libraries supplied
with HP-UX 10.20, 11,00, 11.11, and 11.22 are potentially
vulnerable.
In addition, cross-reference:
HP Tru64 UNIX: Case id: SSRT2309 rpc XDR_ARRAY
A solution is available as noted in the recent
security bulletin SSSRT2275 at
http://thenew.hp.com/country/us/eng/support.html
Use the SEARCH IN feature box, enter SSRT2275 in the
search window.
B. Recommended solution
Until patches are released download and manually install
the appropriate libraries.
Note: It will be necessary to relink any programs that
call xdr_array() and are linked with archived libraries.
There are no known programs supplied by HP which need to
be relinked. To test an archived program:
strings suspect_program | grep xdr_array:
If the command above returns "xdr_array: out of memory"
the suspect_program will need to the relinked with a
fixed library.
Download the appropriate files from:
System: hprc.external.hp.com (192.170.19.51)
Login: xdr
Password: xdr1
FTP Access: hprc.external.hp.com/">ftp://xdr:xdr1
hprc.external.hp.com/
or: 192.170.19.51/">ftp://xdr:xdr1192.170.19.51/
Note: There is an ftp defect in IE5 that may result in
a browser hang. To work around this:
- Select Tools -> Internet Options -> Advanced
- Un-check the option: [ ] Enable folder view for FTP sites.

------------------------------------------------------------------
A. Background
The CERT Advisory CA-2002-17 regarding Apache affects the
following HP products:
B9415AA Apache 1.3.x PA-RISC HP-UX releases 11.00 and 11.11
B9416AA Apache 2.x PA-RISC HP-UX releases 11.00 and 11.11
B9415AA Apache 1.3.x IPF HP-UX releases 11.20 and 11.22
B9416AA Apache 2.x IPF HP-UX releases 11.20 and 11.22
B9416BA Apache 2.x IPv6 PA_RISC HP-UX release 11.11
OpenView NNM 6.01, 6.1, 6.2, 6.31 running on HPUX or SOLARIS
OpenView SIP 1.0, 2.0, 3.0 running on HPUX or SOLARIS
HP Apache 1.3.26 (PA-RISC)
installs into /opt/apache and /opt/tomcat
disk space: 55-65 MB
documents: /opt/apache/htdocs/doc
HP Apache 2.0.39 (PA-RISC)
installs into /opt/hpapache2
disk space: 80-90 MB
documents: /opt/hpapache2/hp_apache_docs
HP Apache 1.3.26 (IPF)
installs into /opt/apache and /opt/tomcat
disk space: 65-75 MB
documents: /opt/apache/hp_apache_docs
HP Apache 2.0.39 (IPF)
installs into /opt/hpapache2
disk space: 80-90 MB
documents: /opt/hpapache2/hp_apache_docs
HP Apache 2.0.39 IP version 6 (PA-RISC)
installs into /opt/hpapache2
disk space: 80-90 MB
documents: /opt/hpapache2/hp_apache_docs
Before updating, make sure to stop your previous HP Apache
binary. Otherwise, the previous binary will continue running,
preventing the new one from automatically starting, although
the installation would have been 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.
==================================================================
An advisory has been issued for HP Compaq systems. Please
