Title: Vulnerability with Large UID's and GID's in HP-UX 10.20
-------------------------------------------------------------------------
**REVISED 02**HEWLETT-PACKARD SECURITY BULLETIN: #00041, 20 January 1997
Last Revised: 29 July 1997
-------------------------------------------------------------------------
The information in the following Security Bulletin should be acted upon
as soon as possible. Hewlett Packard 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: Use of user or group id's greater than 60000
PLATFORM: HP 9000 series 700/800 systems running version 10.20
DAMAGE: Increase in capability and unauthorized access
SOLUTION: **REVISED 01**
Install PHSS_9343, PHNE_9377, and PHNE_9504. Then examine
the system for suid files that may not be safe for a large
uid/gid system. Any such files must be certified by their
providers as safe for use in large uid/gid system.
**REVISED 02**
Apply patch PHSS_11309. PHSS_9799, which superseded
PHSS_9343, inadvertently omitted the fix.
Do not use PHSS_9799; it is now unavailable.
Both PHSS_9343 and PHSS_9799 have been superseded by
PHSS_11309, which does have the fix.
AVAILABILITY: PHSS_9343, PHNE_9377, PHNE_9504 and PHSS_11309 are
available now.
CHANGE SUMMARY: **REVISED 02**
One of the patches needed, PHSS_9343 (hpterm) was
superseded by a patch that omitted the fix, PHSS_9799.
Do not use PHSS_9799. It has been superseded by PHSS_11309.
PHSS_9343 has also been superseded by PHSS_11309. You can
continue to use PHSS_9343. However, PHSS_11309 has additional
defect fixes and you may want to install it.
NOTE: You still need to install PHNE_9377 and PHNE_9504 or
subsequent. You also need to examine the system for suid
files that may not be safe for a large uid/gid system.
-------------------------------------------------------------------------
I.
A. Background
Large user and group id's are new features of HP-UX revision 10.20.
Requirements for a program to work in a large uid/gid system are
detailed in the 10.20 Release Notes. In particular the uid or gid
must not be stored in a short int. Doing so in a suid program
can result in an increase in capability, including root access.
The suid files in the following filesets have been examined and
are free of the security vulnerability (after installing the
patches listed above). This only implies that the files are free
from the vulnerability. It does not necessarily mean that the
programs in that fileset will work properly in a large uid/gid
system.

Note: The fact that a fileset is missing from the list above
does not mean it is suspect. It may mean the fileset contains
no suid files. The script below can be used to identify suid
files that are not contained in known safe filesets.
B. Fixing the problem
Install the patches listed above and examine all suid files.
The following script will identify suspect suid files.
The provider of any suspect file should be contacted to confirm
that the program is safe for use in a large uid/gid system.
Note: The script was tested on a system with one file system.
If you have a different configuration (nfs mounted file systems,
for example), you may want to modify the find(1) command.
Note: Some suid files may be listed under the fileset of
a patch as well as under the primary fileset. In that case:
1. Use swlist to find all the instances of each file.
For example:
# swlist -l file | grep vueaction
PHSS_8537.PHSS_8537: /usr/vue/bin/vueaction
VUE.VUE-MAN: /usr/share/man/man1.Z/vueaction.1
VUE.VUE-RUN: /usr/vue/bin/vueaction
# swlist -l file | grep vuehello
...
2. Verify that the primary (non-patch) fileset is on the
list of large uid/gid safe filesets. In this case
VUE-RUN is on the list.
3. Add the patch fileset (PHSS_8537 in this example) to the
list of safe filesets in the script below. For example:
-e PHSS_8537: \

Title: Buffer overflows in X11/Motif libraries
-------------------------------------------------------------------------
HEWLETT-PACKARD SECURITY BULLETIN: #00067, 30 July 1997
-------------------------------------------------------------------------
The information in the following Security Bulletin should be acted upon
as soon as possible. Hewlett Packard 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: Buffer overflows in X11/Motif libraries.
PLATFORM: HP9000 Series 700/800 running releases 9.X and 10.X
DAMAGE: Suid/sgid programs linked with X11/Motif libraries can
be exploited to increase privileges.
SOLUTION: Install the patches listed below. Any programs that are
linked archived with any previous versions of the X11/Motif
libraries must be relinked with the libraries in the patches.
AVAILABILITY: The patches are available now.
-------------------------------------------------------------------------
I.
A. Background - Several buffer overflow conditions have been
identified. These have been present in all
previous versions of the X11/Motif libraries.
B. Fixing the problem - Install the applicable patches:
PHSS_11626 9.X X11R5/Motif1.2 Runtime
PHSS_11627 9.X X11R5/Motif1.2 Development
PHSS_11043 10.0X X11R5/Motif1.2 Runtime (also for 10.10)
PHSS_11044 10.0X X11R5/Motif1.2 Development
PHSS_11043 10.10 X11R5/Motif1.2 Runtime (also for 10.0X)
PHSS_11045 10.10 X11R5/Motif1.2 Development
PHSS_11628 10.20 X11R5/Motif1.2 Runtime
PHSS_11629 10.20 X11R5/Motif1.2 Development
PHSS_11628 10.20 X11R6/Motif1.2 Runtime
PHSS_11630 10.20 X11R6/Motif1.2 Development
PHSS_9858 9.X VUE 3.0
PHSS_9804 10.01 VUE 3.0
PHSS_9805 10.10/10.20 VUE 3.0
PHSS_11373 9.X JSE A.B9.40
Then relink any suid/sgid programs that use X11 or Motif archived
libraries.
C. Recommended solution - Install the applicable patches and
relink archived suid/sgid programs.
D. Impact of the patch - The fixes are in the X11/Motif patches.
The VUE and JSE patches make use of the libraries in the
X11/Motif patches.

Title: Security Vulnerability in Novell Netware 3.12 on HP-UX
-------------------------------------------------------------------------
HEWLETT-PACKARD SECURITY BULLETIN: #00068, 30 July 1997
-------------------------------------------------------------------------
The information in the following Security Bulletin should be acted upon
as soon as possible. Hewlett Packard 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: Novell Netware 3.12 release B.10.08 or earlier, and B.09.05 or
earlier allows unauthorized users to read files.
PLATFORM: HP 9000 Series 700/800s running only specific releases of HP-UX
9.X and 10.X. See below.
DAMAGE: Allows users unauthorized file read access.
SOLUTION: Apply the following patches as needed:
PHNE_11684 for HP-UX release 9.04, or
PHNE_11341 for HP-UX release 10.01, and
PHNE_11722 for HP-UX release 10.01, or
PHNE_11723 for HP-UX release 10.10, or
PHNE_11724 for HP-UX release 10.20.
AVAILABILITY: All patches are available now.
-------------------------------------------------------------------------
I.
A. Background
Hewlett-Packard Company has discovered a defect in the Novell
Netware 3.12 product running on HP-UX. This defect is seen on
both 9.04 and 10.X operating systems, and allows users to read
files from an unauthorized PC. Native Netware is exempt from
this defect.
NOTE: The product in question only runs on HP-UX releases 9.04,
10.01, 10.10, or 10.20.
B. Fixing the problem
For HP-UX 9.04 users, simply obtain Netware release B.09.08.002
to be used as a full product replacement. This is the patch
PHNE_11684. Installation will require rebooting the server.
For 10.01 users, before continuing to use Netware, first obtain
PHNE_10341 (the full product replacement patch B.10.08) and then
apply patch PHNE_11722 (B.10.08.002). PHNE_11722 will not
install unless PHNE_10341 has been previously installed.
For HP-UX 10.10 and 10.20 update to the Netware B.10.08 release
from the latest application release CD, DART32 or newer.
Then install the appropriate patch (see above).
C. Recommended solution
The patch is a cumulative patch and and fully fixes the
discovered vulnerability.
