SECURITY BULLETIN: HPSBUX0303-251
Originally issued: 18 March 2003
SSRT3509 Potential Security Vulnerability in CIFS/9000 Server
-----------------------------------------------------------------
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: CIFS/9000 Server is potentially vulnerable to altered
SMB/CIFS network messages.
IMPACT: Potential remote root access.
PLATFORM: All HP9000 servers running CIFS/9000 Server versions up
to A.01.09.01 on HP-UX 11.0, 11.11(11i), and 11.22
SOLUTION: HP-UX 11.0/11.11
Download and install the smbd.11.00 file containing the
fix. This file must be manually installed on the
CIFS Server version A.01.09.01.
HP-UX 11.22
The CIFS Server must be disabled until the new
CIFS/9000 Server version A.01.09.02 is available on
software.hp.com
MANUAL ACTIONS: Yes - NonUpdate
HP-UX 11.0/11.11
Install the smbd.11.00 file.
HP-UX 11.22
Disable the CIFS/9000 Server.
AVAILABILITY: The temporary fix, smbd.11.00, is available now.
This bulletin will be revised when web upgrades
are available.
-----------------------------------------------------------------
A. Background
Note: The following are not vulnerable:
HP OpenVMS
HP NonStop Servers
HP Secure Web Servers for HP Tru64 UNIX
HP Secure Web Servers for HP Tru64 OpenVMS
As further information becomes available HP
will provide notice of the availability of any
additional Samba updates through standard security
bulletin announcements and information will be
available from your normal HP Services support channel.
CIFS Server version A.01.09.01 and prior may allow modified
SMB/CIFS messages to cause smbd to overwrite portions of its
own process address space. This could potentially be
exploited to gain root access remotely.
The latest version of CIFS Server adds checks for proper
SMB/CIFS messages to prevent invalid smbd memory accesses.
The Samba team has provided a note describing ways to
limit exposure to this vulnerability and future potential
vulnerabilities. Please refer to Section E below.
B. Recommended solution
If /opt/samba/bin/smbd is present on a system the following
instructions should be followed.
HP-UX 11.0/11.11
================
Update to version A.01.09.01 if running earlier versions of
CIFS Server (available on software.hp.com). Then download
and install the fixed smbd as detailed below.
When available on software.hp.com, install the complete CIFS
Server 2.2d package (version A.01.09.02) to update the entire
product.
Instructions for installing the fixed smbd:
1. Update to CIFS Server version A.01.09.01 if necessary.
The CIFS Server is available on software.hp.com
2. Download new smbd.11.00.gz binary file:
System: hprc.external.hp.com (192.170.19.51)
Login: samba
Password: samba
FTP Access: ftp://samba:sambahprc.external.hp.com/
or: ftp://samba:samba192.170.19.51/
or: ftp hprc.external.hp.com
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
3. Unpack the file with gunzip and verify the cksum or
the md5 sum:
cksum:
3908130721 2555904 smbd.11.00
MD5 (smbd.11.00) = 24eb08b309ea60c6d48e27fcaf66b5f8
Note: If you wish to verify the md5 sum and you do not
have a copy of md5, please refer to:
HPSBUX9408-016
Patch sums and the MD5 program
Note: Using your itrc account security bulletins can be
found here:
http://itrc.hp.com/cki/bin/doc.pl/screen=ckiSecurityBulletin
4. Replace current smbd file with new version:
Back up the original smbd file : /opt/samba/bin/smbd
Stop CIFS/9000 Server if it is running.
Copy the downloaded smbd.11.00 to /opt/samba/bin/smbd
Note: smbd.11.00 is for both HP-UX 11.00 and
HP-UX 11.11 (11i).
Restart CIFS/9000 Server if it had been running.
HP-UX 11.22

E. Samba Team notes on protecting an unpatched Samba server
************************************
Protecting an unpatched Samba server
************************************
This is a note on how to provide your Samba server some
protection against the potential vulnerability even
if you are unable to upgrade to the fixed version
immediately. Even if you do upgrade these suggestions
provide additional levels of protection against possible
future vulnerabilities.
Using host based protection
---------------------------
In many installations of Samba the greatest threat comes from
outside the immediate network. By default Samba will accept
connections from any host.
One of the simplest fixes in this case is to use the 'hosts
allow' and 'hosts deny' options in the Samba smb.conf
configuration file to only allow access to your server from a
specific range of hosts. An example might be:
hosts allow = 127.0.0.1 192.168.2.0/24 192.168.3.0/24
hosts deny = 0.0.0.0/0
The above will only allow SMB connections from 'localhost'
(your own computer) and from the two private networks
192.168.2 and 192.168.3. All other connections will be
refused connections as soon as the client sends its first
packet. The refusal will be marked as a 'not listening on
called name' error.
Using interface protection
--------------------------
By default Samba will accept connections on any network
interface that it finds on your system. That means if you
have a ISDN line or a PPP connection to the Internet then
Samba will accept connections on those links. This may not be
what you want.
You can change this behavior using options like the
following:
interfaces = lan* lo0
bind interfaces only = yes
that tells Samba to only listen for connections on interfaces
with a name starting with 'lan' such as lan0, lan1, plus on
the loopback interface called 'lo0'. The name you will need to
use depends on what OS you are using. The example above uses
the common name for ethernet adapters on HP-UX.
If you use the above and someone tries to make a SMB
connection to your host over a PPP interface called 'ppp0',
they will get a TCP connection refused reply. In that
case no Samba code is run at all as the operating system has
been told not to pass connections from that interface to any
process.
Using a firewall
----------------
Many people use a firewall to deny access to services that
they do not want exposed outside their network. This can be a
very good idea, although the methods above should also be used
in case the firewall is not active for some reason.
If you are setting up a firewall then you need to know what
TCP and UDP ports to allow and block. Samba uses the
following:
UDP/137 - used by nmbd
UDP/138 - used by nmbd
TCP/139 - used by smbd
TCP/445 - used by smbd
The last one is important as many older firewall setups may
not be aware of it, given that this port was only added to
the protocol in recent years.
Using a IPC$ share deny
-----------------------
If the above methods are not suitable, then you could also
place a more specific deny on the IPC$ share that is used in
the vulnerability reported in this bulletin. This allows you
to offer access to other shares while denying access to IPC$
from potentially untrustworthy hosts.
To do that you could use:
[ipc$]
hosts allow = 192.168.115.0/24 127.0.0.1
hosts deny = 0.0.0.0/0
this would tell Samba that IPC$ connections are not allowed
from anywhere but the two listed places (localhost and a
local subnet). Connections to other shares would still be
allowed. As the IPC$ share is the only share that is always
accessible anonymously this provides some level of protection
against attackers that do not know a username/password for
your host.
If you use this method then clients will be given an 'access
denied' reply when they try to access the IPC$ share. That
means that those clients will not be able to browse shares,
and may also be unable to access some other resources.

-----------------------------------------------------------------
PROBLEM: Potential vulnerability regarding miniserv.pl in
(1) Webmin before 1.070, and
(2) Usermin before 1.000 does not properly handle
metacharacters such as line feeds and carriage returns
(CRLF) in Base-64 encoded strings during Basic
authentication, which allows remote attackers to
potentially spoof a session ID and potentially gain root
privileges.
Note: Usermin is currently not shipped in any of the products
mentioned below.
More details are available at:
<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0101>

AVAILABILITY: Complete product bundles are available now on
<http://www.software.hp.com/>
-----------------------------------------------------------------
A. Background
The Common Vulnerabilities and Exposures project
<http://cve.mitre.org/> has identified multiple potential
vulnerabilities in the Webmin GUI Administration tool
(CAN-2003-0101). It affects the following HP product
numbers/versions on HP-UX releases 11.00, 11.11, 11.20
and 11.22::
- hp apache-based web server, 1.3.27.00 or earlier
(ApacheStrong/B9415AA)
- hp apache-based web server, 2.0.43.00 or earlier
(HPApache/B9416AA, HPApache/B9416BA)
- hp-ux webmin-based admin, v.1.0.00.01 or earlier
(hpuxwsWEBMIN/hpuxwsWebmin)
B. Recommended solution
The Webmin Group has released Webmin 1.070 as the best known
version that fixes the problems identified in the above
mentioned issues.
For customers using ApacheStrong/B9415AA, HP has incorporated
Webmin 1.070 in the following products:
- B9415AA: hp apache-based web server 1.3.27.01
This product includes Webmin 1.070.
For customers using HPApache/B9416AA, HPApache/B9416BA and
hpuxwsWEBMIN/hpuxwsWebmin, HP has incorporated Webmin 1.070
in the following products:
- hpuxwsWebmin: hp-ux webmin-based admin v.1.0.01.01 or
later;
This product includes Webmin 1.070.
NOTE: No IPv6 solution is available at this time. This Security
Bulletin will be updated when such becomes available.
Check for Webmin Installation
-----------------------------
To determine if the Webmin GUI Administration Tool from HP
is installed on your system, use Software Distributor's swlist
command. Since Webmin is not visible at the "product" level
for products prior to hpuxwsWEBMIN, search for Apache as well.
All versions of products may co-exist on a single system.
For example, the results of the commands:
swlist -l product | grep -i webmin
hpuxwsWEBMIN A.1.0.00.01 HP-UX Webmin-based Admin
swlist -l product | grep -i apache
ApacheStrong 1.3.19.21 HP Apache-based Web Server
with Strong (128bit) Encryption
HPApache 2.0.39.01.02 HP Apache-based Web Server
In the above examples, all of these need to be updated.
Stop Webmin
-----------------------------
Before updating, make sure to stop any previous Webmin binary.
Otherwise, the previous binary will continue running,
preventing the new one from starting, although the installation
would be successful.
After determining which Webmin is installed, stop Webmin with
the following commands:
for ApacheStrong: /opt/apache/webmin/webmin-init stop
for HPApache: /opt/hpapache2/webmin/webmin-init stop
for hpuxwsWEBMIN: /opt/hpws/webmin/webmin-init stop
Since Webmin is bundled with Apache for products prior to
hpuxwsWEBMIN, Apache also needs to be stopped.
for ApacheStrong: /opt/apache/bin/apachectl stop
for HPApache: /opt/hpapache2/bin/apachectl stop
Download and Install Webmin/Apache
-----------------------------
- Download Webmin/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 hpuxwsWEBMIN/hpuxwsWebmin 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 Webmin Installation
----------------------------
If you rather remove Webmin 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:
For ApacheStrong/B9415AA, HPApache/B9416AA, and
HPApache/B9416BA when removing Webmin, you will also remove
Apache.
%ls /etc/rc.config.d | grep apache
apacheconf
hpapache2conf
NOTE: For HP Apache 1.3.x, you must manually remove the
Apache directory in addition to the Tomcat directory.
Apache is under directory "/opt/apache" for
HP Apache 1.3.x.
For hpuxwsWebmin/hpuxwsWebmin:
%ls /etc/rc.config.d | grep webmin
hpws_webminconf

PROBLEM: Potential vulnerabilities with using Tomcat 3.3.1 or
earlier.
a) When used with JDK 1.3.1 or earlier:
- it allows remote attackers to potentially list
directories even with an index.html or other file

-----------------------------------------------------------------
A. Background
The Common Vulnerabilities and Exposures project
<http://cve.mitre.org/> has identified multiple potential
vulnerabilities in the Jakarta-Tomcat servlet engine
(CAN-2003-0042, CAN-2003-0043, CAN-2003-0044).
It affects the following HP product numbers/versions on
HP-UX releases 11.00, 11.11, 11.20 and 11.22::
- hp apache-based web server, 1.3.27.00 or earlier
(ApacheStrong/B9415AA)
- hp apache-based web server, 2.0.43.00 or earlier
(HPApache/B9416AA, HPApache/B9416BA)
B. Recommended solution
The Apache Group has released Tomcat 3.3.1a as the best known
version that fixes the problems identified in the above
mentioned issues.
For customers using ApacheStrong/B9415AA, HP has incorporated
Tomcat 3.3.1a in the following product:
- hp apache-based web server 1.3.27.01 or later
http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/cgi/
displayProductInfo.pl?productNumber=B9415AA132701
For customers using HPApache/B9416AA and HPApache/B9416BA,
HP has incorporated Tomcat 4.1.12 in the following product:
- hp-ux tomcat-based servlet engine v.1.0.01.01 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.
Check for Tomcat Installation
-----------------------------
To determine if the Tomcat Servlet Engine from HP is installed
on your system, use Software Distributor's swlist command.
Since Tomcat is not visible at the "product" level, search for
Apache. All versions of products may co-exist on a single
system.
For example, the results of the command:
swlist -l product | grep -i apache
ApacheStrong 1.3.19.21 HP Apache-based Web Server
with Strong (128bit) Encryption
HPApache 2.0.39.01.02 HP Apache-based Web Server
Stop Tomcat
-----------------------------
Before updating, make sure to stop any previous Tomcat binary.
Otherwise, the previous binary will continue running,
preventing the new one from starting, although the installation
would be successful.
After determining which Tomcat is installed, stop Tomcat with
the following commands:
for ApacheStrong: /opt/tomcat/bin/shutdown.sh
for HPApache: /opt/hpapache2/tomcat/bin/shutdown.sh
Since Tomcat is bundled with Apache, Apache also needs to be
stopped:
for ApacheStrong: /opt/apache/bin/apachectl stop
for HPApache: /opt/hpapache2/bin/apachectl stop
Download and Install Tomcat and Apache
-----------------------------
- Download Tomcat/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 hpuxwsTOMCAT/hpuxwsTomcat 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.
NOTE: For OV SIP 3.0 and 3.1 users manually upgrade the Tomcat
Application server as a workaround. This security
bulletin will be updated when OV patches become
available.
Removing Tomcat Installation
----------------------------
If you rather remove Tomcat 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
NOTE: Apache will also be removed.
NOTE: For HP Apache 1.3.x, you must manually remove the Apache
directory in addition to the Tomcat directory. Apache is
under directory "/opt/apache" for HP Apache 1.3.x.

PROBLEM: Potential vulnerability regarding ssl3_get_record in
s3_pkt.c for OpenSSL before 0.9.7a and 0.9.6 before
0.9.6i does not perform a MAC computation if an incorrect
block cipher padding is used, which causes an information
leak (timing discrepancy) that may make it easier to
launch cryptographic attacks that rely on distinguishing
between padding and MAC verification errors, possibly
leading to extraction of the original plaintext, aka the
"Vaudenay timing attack."
More details are available at:
