host is prior to 58.0.3029.96. It is, therefore, affected by an
unspecified race condition in the WebRTC component in frame_buffer2.cc
that is triggered during the handling of frame orders. An
unauthenticated, remote attacker can exploit this to have an
unspecified impact.

Note that Nessus has not tested for this issue but has instead relied
only on the application's self-reported version number.");
