B. Recommended solution
**REVISED 06**
--> All versions:
--> =============
--> If the following changes to /etc/mail/sendmail.cf were
--> not done when HPSBUX0304-253 was implemented they should
--> be done now:
--> Modify /etc/mail/sendmail.cf as follows:
--> Add "restrictqrun" to the PrivacyOptions.
--> After the change the line should read:
--> O PrivacyOptions=authwarnings,restrictqrun
--> Patches and web upgrades are now available for
--> B.11.00 and B.11.11. HPSecurityBul281b should
--> be removed before installing the patch or web upgrade:
--> swremove HPSecurityBul281b.INETSVCS-RUN
-->B.11.00:
--> Sendmail 8.9.3 - install PHNE_29773 or subsequent.
--> Sendmail 8.11.1 - install the web upgrade B.11.00.01.005
--> or subsequent.
-->B.11.11
--> Sendmail 8.9.3 - install PHNE_29774 or subsequent.
--> Sendmail 8.11.1 - install the web upgrade B.11.00.01.006
--> or subsequent.
-->B.11.04, B.11.22, and B.11.23:
-->1. Install the patches recommended in HPSBUX0304-253.
-->2. Download and install HPSecurityBul281b.depot
Note: To preserve the original version of sendmail,
HPSecurityBul281a.depot should be removed before
installing HPSecurityBul281b.depot. However,
there is no need to install HPSecurityBul281b.depot
on B.11.00 and B.11.11 systems where
HPSecurityBul281a.depot was previously installed
without error.
The HPSecurityBul281 depot has had two revisions.
The revision history is:
HPSecurityBul281a.depot corrected a packaging
issue with sendmail.893.11.11.r4.
HPSecurityBul281b.depot corrected a packaging
issue with sendmail.811.11.22.r5 and added
sendmail.811.11.23.r1.
The sendmail files in each of these depots are
identical to the unpackaged files listed in
the original version of this bulletin with the
exception of sendmail.811.11.23.r1. This file
is new as of HPSecurityBul281b.depot.
Note: The filenames in HPSecurityBul281 depots
(for example, sendmail.811.11.22.r5) have been
created for these depots. The "r5" is used to
differentiate the file from previous versions
packaged in temporary depots. It bears no
relation to any sendmail revision.
