Right you are, get that improvements to upstream will be the best
solution. Unfortunately no upstream for libjpeg is active so we can't
share TigerVNC code easily.

There were no security issue in libjpeg for ten years (please fix me
if I'm incorrect) so I don't think that vnc will suffer due builtin
jpeg. As written on
http://www.mail-archive.com/tigervnc-devel lists sourceforge net/msg00225.html
TigerVNC consumes approximately 40% less CPU when it uses builtin jpeg
so it is a valid reason, I think.
