iodine - security update

Oscar Reparaz discovered an authentication bypass vulnerability in
iodine, a tool for tunneling IPv4 data through a DNS server. A remote
attacker could provoke a server to accept the rest of the setup or
also network traffic by exploiting this flaw.

For the stable distribution (wheezy), this problem has been fixed in
version 0.6.0~rc1-12+deb7u1.

For the testing distribution (jessie), this problem has been fixed in
version 0.6.0~rc1-19.

For the unstable distribution (sid), this problem has been fixed in
version 0.6.0~rc1-19.

We recommend that you upgrade your iodine packages.
