Package        : yadifa
CVE ID         : CVE-2017-14339
Debian Bug     : 876315

It was discovered that YADIFA, an authoritative DNS server, did not
sufficiently check its input. This allowed a remote attacker to cause
a denial-of-service by forcing the daemon to enter an infinite loop.

For the stable distribution (stretch), this problem has been fixed in
version 2.2.3-1+deb9u1.

We recommend that you upgrade your yadifa packages.
