The file /opt/sharedprint/bin/pcltotiff contains a flaw that allows a local denial of service. This DoS is due to pcltotiff having set group id permissions.
Currently there is not a patch for this issue. However, a workaround is to remove the set group id permissions from the pcltotiff file and allow read access to the file /usr/lib/X11/fonts/ifo.st/typefaces/. This can be accomplished with the commands below:
/sbin/chmod 555 /opt/sharedprint/bin/pcltotiff
/sbin/chmod o+r /usr/lib/X11/fonts/ifo.st/typefaces/
