SSRT3450 HP-UX Bastille sendmail.cf problem
-----------------------------------------------------------------
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: HP has discovered a functional defect in Bastille
B.02.00.00 which caused the sendmail privacy options not
to be configured correctly if that option were chosen.
IMPACT: Not applying the recommended patch may result in
unintended availability of usernames and aliases if the
sendmail daemon is still running. This is the same as the
behavior if you did not choose to restrict the vrfy and
expn commands with Bastille.
PLATFORM: HP-UX 11.00 and HP-UX 11.11
SOLUTION: Install HP-UX Bastille B.02.00.05 or later or
install PHSS_28558 on systems with HP-UX Bastille
B.02.00.00 installed. Either solution completely
addresses this problem.
MANUAL ACTIONS: No.
AVAILABILITY: Both the patch and Bastille B.02.00.05 are available
now.
------------------------------------------------------------------
A. Background
Bastille is a security hardening/lockdown tool which can be
used to enhance the security of the HP-UX operating system. It
provides customized lockdown on a system by system basis by
encoding functionality similar to the Bastion Host whitepaper
and other hardening/lockdown checklists.
Bastille was originally developed by the open source community
for use on Linux systems. HP is contributing by providing
Bastille on HP-UX and helping to improve Bastille on both
platforms.
The functional defect in Bastille B.02.00.00 which caused
sendmail to be improperly configured does not affect
Bastille Linux. If a sendmail daemon is running, the improper
configuration may allow network users to verify the existence
system users as well as expanding sendmail aliases if any are
defined.
Specifically, HP-UX Bastille B.02.00.00 incorrectly configured
the novrfy and noexpn options in sendmail.cf. PHSS_28558 will
fix the problem.
PHSS_28558 has two effects. First, Bastille is modified to
handle the novrfy and noexpn options correctly. Second, if the
novrfy and noexpn options in sendmail.cf had been configured
incorrectly PHSS_28558 will modify sendmail.cf and cause sendmail
to read the corrected configuration.
B. Recommended solution
If B.02.00.00 has been installed either download and install
HP-UX Bastille B.02.00.05 (or later) or apply PHSS_28558.
Bastille B.02.00.05
===================
Download and install HP-UX Bastille B.02.00.05 or later from
http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/cgi/
displayProductInfo.pl?productNumber=B6849AA
("Receive for free" link at the bottom of the page)
Bastille B.02.00.00 and PHSS_28558
==================================
If you have already used Bastille 2.0.0 to configure your
system, only applying PHSS_28558 is necessary. Applying this
patch will fix the sendmail configuration (if applicable to
your system) and the defect in Bastille for future runs.

Title: HP-UX Bastille Announcement

SECURITY BULLETIN: HPSBUX0302-244
Originally issued: 13 February 2003
HP-UX Bastille Announcement
-----------------------------------------------------------------
NOTICE: There are no restrictions for distribution of this Bulletin
provided that it remains complete and intact.
------------------------------------------------------------------
ANNOUNCEMENT: HP-UX Bastille is available to help administrators
proactively implement security best-practices by
turning off and/or configuring operating system
services.
IMPACT: HP-UX is a general purpose operating system, which includes
more services than are needed in most single-purpose
environments. Limiting these services to only the ones you
need in your environment can significantly decrease the risk
of malicious attacks. Bastille does not fix any specific
security vulnerabilities; it can limit exposure to
vulnerabilities, including those which have not yet been
discovered.
PLATFORM: HP-UX 11.00 and HP-UX 11.11
SOLUTION: Install and use HP-UX Bastille to configure appropriate
security settings. If you have already used Bastille
B.02.00.00 please refer to HPSBUX0302-245.
MANUAL ACTIONS: Yes - NonUpdate
Install and use Bastille.
AVAILABILITY: HP-UX Bastille is available now from software.hp.com.

Bastille is a security hardening/lockdown tool which can be

and other hardening/lockdown checklists.
Bastille was originally developed by the open source community
for use on Linux systems. HP is contributing by providing
Bastille on HP-UX and helping to improve Bastille on both
platforms.
All Bastille actions are optional; installing Bastille will not
take action on your system. Running the Bastille user interface
is the best way to create an appropriate system configuration,
which can then be applied or even duplicated on other systems.
B. Recommended solution
Download, install, and run HP-UX Bastille B.02.00.05 or later
from http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/cgi/
displayProductInfo.pl?productNumber=B6849AA
("Receive for free" link at the bottom of the page)
The interactive Bastille interface will guide you through
security tradeoffs and let you choose exactly which steps to
take to secure your system. Bastille can then automatically
apply all of your choices to the system. You may also choose
to apply the same configuration to other systems.
HP recommends that you re-run Bastille after installation of
patches or software to ensure continued conformance with the
settings that you have chosen. (It is possible that new software
or patch installation may undo security configuration changes you
make with Bastille or manually.)
