   HEWLETT-PACKARD COMPANY SECURITY ADVISORY #0149, 19 April 2001
-------------------------------------------------------------------------

The information in the following Security Advisory 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 Advisory as soon as possible.

-------------------------------------------------------------------------
PROBLEM:  /opt/sharedprint/bin/pcltotiff has unsafe permissions.

PLATFORM:  HP9000 Series 700/800 running HP-UX releases 10.01,
          10.10, 10.20, 10.26

DAMAGE:  Denial of service.

SOLUTION:  Change the permissions on /opt/sharedprint/bin/pcltotiff.

AVAILABILITY:  This advisory will be upgraded to a bulletin when patches
              are available.

-------------------------------------------------------------------------
I.
  A. Background

      /opt/sharedprint/bin/pcltotiff is in group bin with set group id
     permissions.  This is necessary to allow pcltotiff to read files
     in /usr/lib/X11/fonts/ifo.st/typefaces/.

   B. Fixing the problem

      Remove the set group id permissions from pcltotiff and
     allow read access to /usr/lib/X11/fonts/ifo.st/typefaces/.

   C. Recommended solution

      /sbin/chmod 555 /opt/sharedprint/bin/pcltotiff
     /sbin/chmod o+r /usr/lib/X11/fonts/ifo.st/typefaces/*

      To avoid swverify errors:

      #!/sbin/sh
     /usr/sbin/swmodify -x files='/opt/sharedprint/bin/pcltotiff' \
       SharedPrint.SHPRNT-PCL

       for i in `/sbin/ls /usr/lib/X11/fonts/ifo.st/typefaces`
      do
       /usr/bin/swmodify \
         -x files='/usr/lib/X11/fonts/ifo.st/typefaces/$i' \
         X11.X11-FONTSRV
     done
