HP NonStop Servers,
HP Tru64 UNIX/TruCluster Server,
HP OpenVMS
HP-UX VVOS (11.04)
The SSRT thanks LSD Research Group (http://lsd-pl.net) for
reporting this potential vulnerability to HP.
B. Recommended solution
The following temporary depot files MUST be removed before
the official patch is installed. Failure to properly remove
these could cause corruption of the system and inadvertently
re-introduce the problem at a later time when the temporary
patch is removed.
The temporary files to be removed were:
for HP-UX 11.00 PHCO_29106.depot
for HP-UX 11.11 UNOF_29107.depot
Now apply the appropriate patch:
PHCO_29382 for B.11.11
PHCO_29381 for B.11.00
Download the patch from itrc.hp.com, copy the depot to a
protected directory, and launch Software Distributor (SD)
to install.
On systems running the discontinued and obsoleted B.10.20
continue to use the temporary depot: PHCO_29105.depot.

listed in the Security Patch Matrix will completely
implement a security bulletin _only_ if the MANUAL ACTIONS
field specifies "No."
The Security Patch Check tool can verify that a security
bulletin has been implemented on HP-UX 11.XX systems providing
that the fix is completely implemented in a patch with no
manual actions required. The Security Patch Check tool cannot
verify fixes implemented via a product upgrade.
