 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
