I'm not convinced, having seen some very sophisticated attacks here,
using combinations of known low level web service exploits combined
with recently published local exploits to get root access.  The ones I
saw used a java/structs exploit plus a glib bug that should have been
fixed in 5.4, but it was pretty clear that attempts were being made in
a coordinated way to use recently published vulnerabilities.  Not sure
what might have been left in 5.5, though.
