[SECURITY] Fedora 17 Update: libzrtpcpp-2.3.4-1.fc17

This package provides a library that adds ZRTP support to the GNU ccRTP stack. Phil Zimmermann developed ZRTP to allow ad-hoc, easy to use key negotiation to setup Secure RTP (SRTP) sessions. GNU ZRTP together with GNU ccRTP (1.5.0 or later) provides a ZRTP implementation that can be directly embedded into client and server applications.
