Potential Denial of Service (DoS).
PLATFORM: MPE 7.0 and 7.5 running Sendmail 8.12.1 A.01.00, or

versions of sendmail.
SOLUTION: Download and install the appropriate sendmail patch

MPE/iX 6.5 (and earlier) SMLGDT8A then SMLHD15A.
(requires manual installation -- see below)
MANUAL ACTIONS: Yes - Non-HP-UX only
see below.
AVAILABILITY: All patches are available now on itrc.hp.com
-----------------------------------------------------------------
A. Background
A potential security vulnerability with sendmail/iX 8.12.1
A.01.01 has been reported in MPE/iX. This potential
vulnerability may result a remote Denial of Service (DoS)
and unauthorized Privilege Access.
This is the vulnerability reported in CERT/CC CA-2003-12.
It should be noted that while sendmail on Unix may allow for
the execution of arbitrary code via a buffer overflow, that
does not apply on MPE/iX, where a buffer overflow would
simply result in a process abort.

SRB SSRT3531 Bulletin for HP Tru64 UNIX,
NOTE: This problem does not impact HP NonStop Servers nor
HP OpenVMS.
The bulletin will be posted to the customer support website
