As I understand it, the attached patch is basically how Microsoft fixed
the recent WMF issue (MS06-001) [1].  It doesn't appear to be fixed in
WineX CVS, although some distros have updated Wine to fix a similar
issue [2].

I assume WineX is vulnerable to something similar, since the Escape()
handler in graphics/escape.c does in fact call SetAbortProc() when it
sees a SETABORTPROC escape.  Should the attached patch be applied?
