Details

Coturn is a free open source implementation of TURN and STUN Server. Prior to 4.16.0, addrlesseq() in src/client/nsturnioaddr.c uses a component-wise comparison for native IPv6 min-max intervals in ioaaddrin_range(), allowing an authenticated TURN client to relay to an IPv6 peer that is numerically within a configured non-prefix-aligned denied-peer-ip range but is classified as outside it. This issue is fixed in version 4.16.0.
