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

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.
