## Description

The \_udp\_lib\_get\_port function in net/ipv4/udp.c in Linux kernel 2.6.21 and
earlier does not prevent a bind to a port with a local address when there
is already a bind to that port with a wildcard local address, which might
allow local users to intercept local traffic for daemons or other
applications.

Cannot reproduce. Is this really an issue for kernels prior to 2.6.21?
