SSRT3622 Security Bulletin rev.1 - HP-UX AAA 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: 1. Certain ASN.1 encodings that are rejected as invalid
by the parser can trigger a bug in the deallocation
of the corresponding data structure, corrupting the
stack. This can be used as a denial of service
attack. It is currently unknown whether this can be
exploited to run malicious code. This issue does not
affect OpenSSL 0.9.6.
More details are available at:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0545
2. Unusual ASN.1 tag values can cause an out of bounds
read under certain circumstances, resulting in a
denial of service vulnerability.
More details are available at:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0543
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0544
3. A malformed public key in a certificate will crash
the verify code if it is set to ignore public key
decoding errors. Exploitation of an affected
application would result in a denial of service
vulnerability.
4. Due to an error in the SSL/TLS protocol handling,
a server will parse a client certificate when one is
not specifically requested.
IMPACT: Potential Denial of Service
PLATFORM: HP9000 Servers running HP-UX release B.11.00, B.11.11
with HP-UX AAA Server, A.06.01.02 or earlier,
(AAAServer/T1428AA)
This product included OpenSSL 0.9.7b.
**REVISED 01**
SOLUTION: For HP-UX releases B.11.00, B.11.11, download new
HP-UX AAA Server product from <software.hp.com>
For AAAServer/T1428AA download the following:
- HP-UX AAA Server
A.06.01.02.04 or later (AAAServer)
This product includes OpenSSL 0.9.7b + patches.
MANUAL ACTIONS: Yes - Update
Install the product containing the fix.
Remove AAAServer (T1428AA) and migrate to
HP-UX AAA Server A.06.01.02.04 or later.
AVAILABILITY: Complete product bundles are available from
<software.hp.com>.
CHANGE SUMMARY: Rev. 1 - product bundles are available from
<software.hp.com>,
ftp site has been removed.
-----------------------------------------------------------------
A. Background
An SSL/TLS testing suite developed by the NISCC (National
Infrastructure Security Co-Ordination Centre in the UK) has
identified ASN.1 parsing vulnerabilities in OpenSSL.
The HP-UX AAA Server (T1428AA) is affected by latest OpenSSL
vulnerabilities.
AFFECTED VERSIONS
==================
The following is a list by HP-UX revision of
affected filesets or patches and fix information.
To determine if a system has an affected version,
search the output of "swlist -a revision -l fileset"
for an affected fileset or patch, then determine if
a fixed revision or applicable patch is installed.
The affected filesets are: (product.fileset)
==================
HP-UX B.11.00
HP-UX B.11.11
AAAServer
fix: install revision A.06.01.02.04 or subsequent
END AFFECTED VERSIONS
**REVISED 01**
B. Recommended solution
For customers using the HP-UX AAA Server (T1428AA)
--> revision A.06.01.02 and earlier, download the depot from
<software.hp.com>.
==================================================
To fix the problem:
1. Determine the affected version.
2. Remove HP-UX AAA Server (T1428AA)
3. Install the appropriate HP-UX AAA Server depot.
The fix requires removing AAAServer (T1428AA) from
the system and migrating to HP-UX AAA Server
A.06.01.02.04 or later.
--> NOTE: Even if you recently installed the depot from the
--> ftp site, product users should overwrite the
--> previous downloads of this version A.06.01.02.04
--> with the latest one from software.hp.com. There
--> are changes in the pre- and post-install control and
--> SD scripts.
--> It is not necessary to remove the installed version.
Check for AAA Installation
--------------------------
To determine if the HP-UX AAA Server is installed on
your system, use Software Distributor's swlist command.
For example, the results of the command
swlist -l product | grep -i AAA might show:
AAAServer A.06.01.02 AAA Server
Stop HP-UX AAA Server
---------------------
Before updating, make sure to stop any previous HP-UX AAA
Server binary. Otherwise, the previous binary will continue
running, preventing the new one from starting, although the
installation may be successful.
After determining which HP-UX AAA Server is installed, stop
the process with the following command:
kill `cat /var/opt/aaa/run/radiusd.pid | awk '{print $1}'`
Stop any active tomcat processes using the following command:
/opt/hpws/tomcat/bin/shutdown.sh
**REVISED 01**
Download and Install HP-UX AAA Server
-----------------------------
--> - Download HP-UX AAA Server depot file from software.hp.com.
--> - Register the depot using "swreg" and install using the
--> "swinstall" SD commands.
- Remove AAAServer (T1428AA) and migrate to
HP-UX AAA Server A.06.01.02.04 or later.
Installation of this new version of HP-UX AAA Server
over an existing HP-UX AAA Server installation is supported,
while installation over any non-HP AAA Server is NOT
supported.
Removing an HP-UX AAA Server Installation
----------------------------
If you rather remove HP-UX AAA Server from your system than
install a newer version to resolve the security problem, use
both Software Distributor's "swremove" command.
Note: Before executing swremove, stop HP-UX AAA Server and
the active tomcat processes.
Remove the HP-UX AAA Server using SD command: swremove T1428AA
