d. Install the appropriate file as follows:
Copy the appropriate sendmail file to a protected directory
such as /usr/sbin. If you are running sendmail 8.9.3 also
copy the appropriate killsm file to a protected directory
such as /usr/sbin.
Login as root and run killsm:
killsm
Verify the sendmail daemon is not running:
ps -ef | grep sendmail
If you are running the 8.9.3 version of sendmail
replace killsm as follows:
cd /usr/sbin
cp killsm killsm.orig
cp killrm.893.10.20 killsm
OR
cp killrm.893.11.00 killsm
OR
cp killrm.893.11.11 killsm
**REVISED 01**
--> If you are runnimg 11.22:
--> cd /usr/sbin
--> cp killsm killsm.orig
--> cp killrm.811.11.22 killsm
For all versions of sendmail,
make a backup copy of the existing sendmail:
cd /usr/sbin
cp sendmail sendmail.original
Note the permissions for reference:
ls -lia /usr/sbin/sendmail
Install the new sendmail:
cp sendmail.xxx.yy.zz.rn sendmail
For example, on 11.11:
cp sendmail.811.11.11.r2 sendmail
Restart sendmail.
If you were running sendmail before the killsm
command above, you can now restart it with the
following command (for HP-UX, not VVOS):
/sbin/init.d/sendmail start
Note: Do not execute the command above for VVOS 11.04
The command runs sendmail as a daemon, which is
not supported by VVOS (Virtual Vault Operating
System).
--> End of Step 5.
==================================================
Note: If you receive either of the following messages after
applying the fix, please follow the recommended action.
warning: /etc/mail/aliases has world read or
write permission. This is unsafe.
warning: /etc/mail/aliases.db has world read or
write permission. This is unsafe.
Recommended action
Execute the following commands.
chmod 640 /etc/mail/aliases

3. Download and install either HPSecurityBul246.depot
(this step) or the appropriate sendmail file
(step 4 below).
Until patches are available there are two ways to fix the
problem. Individual sendmail files can be downloaded and
installed as described in previous versions of this
bulletin (step 4 below).
Alternatively a depot can be downloaded and installed using
swinstall(1). The depot contains all of the sendmail
files. The depot determines the correct version to be
installed on each system.
Download and install HPSecurityBul246.depot.gz:
a. Download HPSecurityBul246.depot.gz
b. Unpack the file with gunzip(1)
c. Verify the cksum or the md5 sum.
cksum HPSecurityBul246.depot
3826367137 7198720 HPSecurityBul246.depot
md5 HPSecurityBul246.depot
MD5 (HPSecurityBul246.depot) =
2a81bb91b94bffea13687ce5e1060cef
d. Extract the "readme" file for further information:
cd directory_containing_depot
swlist -d -l product -a readme
$PWD/HPSecurityBul246.depot
e. Install HPSecurityBul246.depot with swinstall(1).
4. Download and install the appropriate file.
Note: The depot mentioned in step 3 above contains all
the sendmail files. If you prefer to download and
install only the files needed for a given revision,
please use the following instructions:
a. Download the appropriate file.
For HP-UX 10.10: sendmail.886.10.10.gz for 8.8.6
For HP-UX 10.20: sendmail.893.10.20.gz for 8.9.3
For HP-UX 11.00: sendmail.811.11.00.gz for 8.11.1
sendmail.893.11.00.gz for 8.9.3
For HP-UX 11.04: sendmail.893.11.00.gz for 8.9.3
For HP-UX 11.11: sendmail.811.11.11.r1.gz for 8.11.1
sendmail.893.11.11.gz for 8.9.3
For HP-UX 11.22: sendmail.811.11.22.gz for 8.11.1
b. Unpack the file with gunzip(1)
c. Verify the cksum or the md5 sum.
cksum:
2052507672 401408 sendmail.886.10.10
3975773765 806912 sendmail.893.10.20
2575934578 970752 sendmail.811.11.00
905487102 827392 sendmail.893.11.00

3842273936 860160 sendmail.893.11.11
3819176330 2281732 sendmail.811.11.22
Note: If you wish to verify the md5 sum and you do not
have a copy of md5, please refer to:

MD5 (sendmail.811.11.22) = 9871b8fd59f9aa39e66da2185681710e
d. Install the appropriate file as follows:
Copy the file to a protected directory such as /usr/sbin.
Login as root and run killsm:
killsm
Verify the sendmail daemon is not running:
ps -ef | grep sendmail
Make a backup copy of the existing sendmail:
cd /usr/sbin
cp sendmail sendmail.original
Note the permissions for reference:
ls -lia /usr/sbin/sendmail
Install the new sendmail:
cp sendmail.xxx.yy.zz sendmail
For example, on 11.22:
cp sendmail.811.11.22 sendmail
Restart sendmail.
If you were running sendmail before the killsm
command above, you can now restart it with the
following command (for HP-UX, not VVOS):
/sbin/init.d/sendmail start
Note: Do not execute the command above for VVOS 11.04
If you are running VVOS (Virtual Vault Operating
System) please do not start the sendmail daemon.
VVOS support does not allow for a sendmail daemon
to be running.
