Status: General Release

Critical: No

Path Name:  /hp-ux_patches/s700_800/10.X/PHNE_6831

Symptoms:
        PHNE_6831:
        * Dead.letter could not be created if one did not exist
          already.

        PHNE_6769:
        * Email addresses that included a quote string containing
          a blank space were truncated after the blank space on
          local delivery.  This prevented many X400 addresses
          from being used.

        PHNE_6406:
        * User could create symbolic links to various files and
          cause mail to read or write to those files, if those
          files existed in group mail readable directories.

Defect Description:
        PHNE_6831:
        * The unlink() procedure was always called regardless of
          whether the file existed.

        PHNE_6769:
        * The From line was parsed using sscanf which uses the blank
          space as a delimiter. This was changed to properly parse
          quoted names in email addresses.

        PHNE_6406:
        * No checks were made to prevent this problem.

Installation Instructions:
        Please review all instructions and the Hewlett-Packard
        SupportLine User Guide or your Hewlett-Packard support terms
        and conditions for precautions, scope of license,
        restrictions, and, limitation of liability and warranties,
        before installing this patch.
        ------------------------------------------------------------
        1. Back up your system before installing a patch.

        2. Login as root.

        3. Copy the patch to the /tmp directory.

        4. Move to the /tmp directory and unshar the patch:

                cd /tmp
                sh PHNE_6831

        5a. For a standalone system, run swinstall to install the
            patch:

                swinstall -x autoreboot=true -x match_target=true \
                        -s /tmp/PHNE_6831.depot

        5b. For a homogeneous NFS Diskless cluster run swcluster on the
            server to install the patch on the server and the clients:

                swcluster -i -b

            This will invoke swcluster in the interactive mode and
            force all clients to be shut down.

            WARNING: All cluster clients must be shut down prior to the
                     patch installation.  Installing the patch while the
                     clients are booted is unsupported and can lead to
                     serious problems.

            The swcluster command will invoke an swinstall session in which
            you must specify:

                alternate root path  -  default is /export/shared_root/OS_700
                source depot path    -  /tmp/PHNE_6831.depot

            To complete the installation, select the patch by choosing
            "Actions -> Match What Target Has" and then "Actions -> Install"
            from the Menubar.

        5c. For a heterogeneous NFS Diskless cluster:

                - run swinstall on the server as in step 5a to install
                  the patch on the cluster server.

                - run swcluster on the server as in step 5b to install
                  the patch on the cluster clients.  The cluster clients
                  must be shut down as described in step 5b.

        By default swinstall will archive the original software in
        /var/adm/sw/patch/PHNE_6831.  If you do not wish to retain a
        copy of the original software, you can create an empty file
        named /var/adm/sw/patch/PATCH_NOSAVE.

        Warning: If this file exists when a patch is installed, the
                 patch cannot be deinstalled.  Please be careful
                 when using this feature.

        It is recommended that you move the PHNE_6831.text file to
        /var/adm/sw/patch for future reference.

        To put this patch on a magnetic tape and install from the
        tape drive, use the command:

                dd if=/tmp/PHNE_6831.depot of=/dev/rmt/0m bs=2k
