Vulnerability Note VU#314776

Original Release Date: 2001-08-15 | Last Revised: 2001-08-17


The utility pcltotiff is installed with insecure permissions on some Hewlett Packard systems.


The HP utility pcltotiff is installed with sgid bin permissions in order to read files in /usr/lib/X11/fonts/ This gives more permissions to pcltotiff than are required. For more information, see HP Security Bulletin HPSBUX0104-149.


The complete impact of this vulnerability is not yet known. Hewlett Packard lists the impact as "Denial of service," but it is unclear why.


Change the permissions on the file as described in HP bulletin.

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

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

  A. Background

      /opt/sharedprint/bin/pcltotiff is in group bin with set group id

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

   C. Recommended solution

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

      To avoid swverify errors:

     /usr/sbin/swmodify -x files='/opt/sharedprint/bin/pcltotiff' \

       for i in `/sbin/ls /usr/lib/X11/fonts/`
