This one is quite old.  As referenced in the above URL, enq is fixed by APAR
IY08143.  The vulnerability was resolved in filesets:

bos.rte.printers:4.3.3.1
printers.rte:4.3.3.11

You appear to be overflowing the input method identifier here.  I don't see
anything explicitly mentioning this vulnerability in IBM's patch database.  I
would be very interested in seeing the output of 'oslevel -r' and
'lslpp -al X11.apps.aixterm' on your test system.
