      NeXT SECURITY BULLETIN: NeXT-94:001-sendmail, 16 February 94
------------------------------------------------------------------------

PROBLEM:
        A security vulnerability has been identified in all versions of
        NEXTSTEP up to and including Release 3.2. This vulnerability,
        described in CERT advisories CA-93:16 and CA-93:16a, may allow
        unauthorized remote or authorized local users to gain unauthorized
        privileges. All sendmail recipient machines within a domain could
        potentially be vulnerable.

SOLUTION:
        NeXT has corrected this vulnerability and provided a patch containing
        new binaries for both NeXT and Intel-based computers running NEXTSTEP
        Release 3.1 or Release 3.2.

DETAILS:
        This patch is available via anonymous FTP from FTP.NEXT.COM in the
        directory "/pub/NeXTanswers/Files/Patches/SendmailPatch.23950.1".

        This patch is for NEXTSTEP 3.1 and NEXTSTEP 3.2. Instructions for
        installing this patch are included in the ReadMe file.

        Note: At the present time, NeXT has no plans to make a patch available
              for releases of NEXTSTEP prior to Release 3.1.

COMMENTS:
        NeXT recommends that all customers concerned with the security of
        their NEXTSTEP systems either apply the patch or edit the sendmail
        configuration files as soon as possible.
