A. Background
Certain network traffic can cause programs to fail. An
example of a potentially vulnerable program is nfsd.
AFFECTED VERSIONS
The following is a list by HP-UX revision of
affected filesets and the fileset revision or
patch containing the fix. To determine if a
system has an affected version, search the
output of "swlist -a revision -l fileset"
for an affected fileset, then determine if
a fixed revision or the applicable patch is
installed.
HP-UX B.11.22
=============
Streams.STREAMS-64SLIB
fix: install libxti.2-pa20_64-perf and libxti.so.1-em_64-perf
Streams.STREAMS-MIN
fix: install libxti.2-pa11-perf and libxti.so.1-em_32-perf
HP-UX B.11.11
=============
Streams.STREAMS-MIN
fix: PHNE_27703 or subsequent
HP-UX B.11.00
=============
Streams.STREAMS-MIN
fix: PHNE_27702 or subsequent
END AFFECTED VERSIONS
B. Recommended solution
HP-UX B.11.00 - Install PHNE_27902 or subsequent
HP-UX B.11.11 - Install PHNE_27703 or subsequent
HP-UX B.11.22 - Download and install the fixed linrary
files as follows:

a. Download the files into a protected directory
such as /etc.
b. Unpack the files with gunzip(1)
c. Verify the cksum or the md5 sum.

It is not necessary to reboot the system. However,
currently executing programs will continue to use the
original libraries until they are restarted. Rebooting
the system insures that all programs use the new libraries.

To -gain access- to the Security Patch Matrix, select
the link for "The Security Bulletins Archive". (near the
bottom of the page) Once in the archive the third link is
to the current Security Patch Matrix. Updated daily, this
matrix categorizes security patches by platform/OS release,
and by bulletin topic. Security Patch Check completely
automates the process of reviewing the patch matrix for
11.XX systems. Please note that installing the patches
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.
For information on the Security Patch Check tool, see:
