OK, found it at http://www.securityfocus.com/bid/5808.  Discussion
says:

  gv is a freely available, open source Portable Document Format (PDF)
  and PostScript (PS) viewing utility. It is available for Unix and
  Linux operating systems.

  It has been reported that an insecure sscanf() function exists in
  gv. Due to this function, an attacker may be able to put malicious
  code in the %%PageOrder: portion of a file. When this malicious file
  is opened with gv, the code would be executed in the security
  context of the local user.

Note that this refers to gv, not ghostview.  It's also incorrect with
ghostview 1.5.  The binary doesn't contain a sscanf() function.  I've
tried the exploit, and it didn't work.  I'll check further, but I
think this one can be allowed again.
