o  Security Bulletin Digest Split
  ------------------------------

   The security bulletins digest has been split into multiple digests
  based on the operating system (HP-UX, MPE/iX, and HP Secure OS
  Software for Linux).  You will continue to receive all security
  bulletin digests unless you choose to update your subscriptions.

  using your IT Resource Center User ID and Password.

   Under the notifications section (near the bottom of the page), select
  Support Information Digests.

   To subscribe or unsubscribe to a specific security bulletin digest,
  select or unselect the checkbox beside it. Then click the
  "Update Subscriptions" button at the bottom of the page.

 ------------------------------------------------------------------

 A. Background
   A buffer overrun has been discovered in the HP CIFS Server
   version A.01.09 and earlier. There is no known exploit of
   this vulnerability, and the Samba Team has not been able to
   craft one themselves.
   Nevertheless, the Samba Team has judged the vulnerability
   significant and announced the defect and fix in their latest
   release.  HP has integrated the fix into the latest release
   of CIFS Server 2.2
   For additional details, see:
     
http://www.samba.org/samba/whatsnew/samba-2.2.7.html

Source: HEWLETT-PACKARD COMPANY
SECURITY BULLETIN: HPSBUX0212-231
Originally issued: 11 December 2002
SSRT2434  Security vulnerability with HP-UX Visualize Conference
-----------------------------------------------------------------

NOTICE: There are no restrictions for distribution of this Bulletin
provided that it remains complete and intact.

The information in the following Security Bulletin should be
acted upon as soon as possible.  Hewlett-Packard Company will
not be liable for any consequences to any customer resulting
from customer's failure to fully implement instructions in this
Security Bulletin as soon as possible.

 ------------------------------------------------------------------
PROBLEM: The installation of HP-UX Visualize Conference leaves
        certain directories with insecure permissions.

IMPACT: Potential increase in privileges, unauthorized access.

PLATFORM: HP 9000 Series 700 and 800, HP-UX 11.00 and 11.11 systems
         which have ever installed HP-UX Visualize Conference
         version B.11.00.11.

SOLUTION: Change the insecure directory permissions.

MANUAL ACTIONS: Yes - NonUpdate
               Change ownership and permissions as follows:
                /etc/dt                     755 bin/bin
                /etc/dt/appconfig           755 root/sys
                /etc/dt/appconfig/icons     755 root/sys
                /etc/dt/appconfig/icons/C   755 root/sys
                /etc/dt/appconfig/types     755 root/sys
                /etc/dt/appconfig/types/C   755 root/sys

AVAILABILITY:  This bulletin will be revised when a product
              update is available.
------------------------------------------------------------------
A. Background
   If HP-UX Visualize Conference version B.11.00.11 has ever been
   installed on an 11.00 or 11.11 system the permissions of
   certain directories may be insecure.

    The installation of HP-UX Visualize Conference may leave
   certain directories with insecure permissions.  The
   vulnerability is not with the HP-UX Visualize Conference
   product itself, but rather with the state of the directory

    permissions after HP-UX Visualize Conference has been installed.
   The vulnerability remains even after HP-UX Visualize Conference
   is removed.

    The problem arises if the directories do not exist at the time
   HP-UX Visualize Conference version B.11.00.11 is installed.
   Therefore not all systems with HP-UX Visualize Conference
   version B.11.00.11 are vulnerable.  Also once the directory
   permissions are corrected a subsequent reinstallation of
   HP-UX Visualize Conference version B.11.00.11 will not alter
   the permissions.

 B. Recommended solution

    Change the insecure directory permissions using the following
   procedure or the equivalent:

    As root create a script "chown_chmod":

      #!/sbin/sh
     # chown_chmod root:sys 755 file
     chown $1 $3
     chmod $2 $3

    Then:

      chown_chmod bin:bin  755 /etc/dt
     chown_chmod root:sys 755 /etc/dt/appconfig
     chown_chmod root:sys 755 /etc/dt/appconfig/icons
     chown_chmod root:sys 755 /etc/dt/appconfig/icons/C
     chown_chmod root:sys 755 /etc/dt/appconfig/types
     chown_chmod root:sys 755 /etc/dt/appconfig/types/C
