This is fixed with the following APARs:

  Abstract:   "HOT: CERT: possible buffer overflow in finger daemon"
  4.1.x APAR: IX67317
  4.2.x APAR: IX67318
  4.3.x APAR: not vulnerable

IBM AIX APARs may be ordered using Electronic Fix Distribution (via the
FixDist program), or from the IBM Support Center.  For more information
on FixDist, and to obtain fixes via the Internet, please reference

        http://aix.software.ibm.com/support/rs6000

or send email to "aixservat_private" with the word "FixDist" in the
"Subject:" line.

To facilitate ease of ordering all security related APARs for each AIX
release, security fixes are periodically bundled into a cumulative APAR.
For more information on these cumulative APARs including last update and
list of individual fixes, send email to "aixservat_private" with
the word "subscribe Security_APARs" in the "Subject:" line.
