PLATFORM: HP 9000 series 700 and series 800 at revisions 9.X
DAMAGE: Users can gain unauthorized privileges
SOLUTION: Apply the appropriate patch for your version of HP-UX
For HP-UX 9.09+ (BLS), apply patch PHKL_5190,
HP-UX 9.09 (BLS), apply patch PHKL_5191,
HP-UX 9.08 (BLS), apply patch PHKL_5192,
HP-UX 9.05, apply patch PHKL_5049,

HP-UX 9.01, apply patch PHKL_5048,
HP-UX 9.0 , apply patch PHKL_5050.
AVAILABILITY: All patches are available now.
-----------------------------------------------------------------------------
A. Problem
Hewlett-Packard has discovered some malicious coding sequences that can
cause the HP-UX Operating System to crash. These coding sequences are
malicious in origin and not representative of compiler generated code.
The resulting system crash is not always predictable, depending heavily
on the state of the system at the time of the attack. Given this
uncertainty, it is feasible that the security and/or integrity of the
system might become compromised.
Having identified this type of system vulnerability, HP has developed a
patch that when installed provides the following countermeasures.
First, it will protect your system from privilege violations that might
be attempted using these malicious coding sequences. Secondly, it
strengthens the Operating System so that it is more resistant to this
type of attack. Should the attack succeed in crashing the system, this
patch will in most cases report the identity of the process and user
that executed the malicious coding sequences. System Administrators
can use this identification information to help track down the source
of such attacks on their system.
B. What the Patch Does
This patch replaces key HP-UX library routines
C. How to Get The Patch
For HP-UX BLS product patches PHKL_5190, PHKL_5191 & PHKL_5192 are NOT
electronically available. For assistance in obtaining and installing
this patch contact the HP Response Center at 1 (800) 633-3600.
Be sure to mention the keyword "BLS" to help route the call.
All the other patches are available electronically. You can retrieve a
patch by using the service described below.
D. How to Install The Patch
1. Determine which patch is appropriate for your hardware platform and
operating system:
On the BLS product, HP-UX 9.08 (series 800) & HP-UX 9.09 (series 700),
execute: what /hp-ux .
On commercial products HP-UX 9.X (series 800) & HP-UX 9.X (series 700),
execute: what /hp-ux . Look for the product 9245XA (series 800) and
B2352A (series 700) to identify the revision currently running.
Then use the table above to select the appropriate patch to request or
retrieve.
2. Hewlett Packard's HP-UX patches are available via email & WWW (MOSAIC)
To obtain a copy of the HP SupportLine email service user's guide,
send the following in the TEXT PORTION OF THE MESSAGE to
support@support.mayfield.hp.com (no Subject is required):

via email and other services available.
WWW (MOSAIC) service (downloading of patches) is
also available via WWW (MOSAIC) our URL is:
(http://support.mayfield.hp.com)
3. Apply the patch to your HP-UX system.
4. Examine /tmp/update.log for any relevant WARNINGs or ERRORs. This
can be done as follows:
a. At the shell prompt, type "tail -60 /tmp/update.log | more"
b. Page through the next three screens via the space bar, looking
for WARNING or ERROR messages.
E. Impact of the patch and workaround
No patches will be available for versions of HP-UX prior to 9.0.
F. How to get Help
If you need help installing a patch and have a Support Contract you
can call the HP Response Center at 1 (800) 633-3600. If you have no
Support Contract, call the same number and ask to make a "Helpline"
call for assistance (payable via credit card).
