Package: netcat-traditional Version: 1.10-40 Severity: normal If netcat is used to connect to a closed local port, it may connect to itself.
How to reproduce: 1) Select a random port from the range which is used by clients # sysctl net.ipv4.ip_local_port_range 2) Start netcat in loop with this port # while true; do nc.traditional -v localhost 52804 < /dev/zero; done localhost [127.0.0.1] 52804 (?) : Connection refused localhost [127.0.0.1] 52804 (?) : Connection refused [....] localhost [127.0.0.1] 52804 (?) : Connection refused localhost [127.0.0.1] 52804 (?) : Connection refused localhost [127.0.0.1] 52804 (?) open The new version netcat-openbsd has the same bug (Filled under #682444). It may be just coincidence, but it looks like that this version is less prone for this bug.
