"It was discovered that the maintainer scripts of pdns-backend-mysql
grant too wide database permissions for the pdns user. Other backends
are not affected.

For Debian 7 'Wheezy', these problems have been fixed in version
3.1-4.1+deb7u1.

Note that if you're running the pdns server with the mysql backend
these additional grants are not removed automatically since they might
have been added on purpose. Check

/usr/share/doc/pdns-backend-mysql/NEWS.Debian.gz

on how to remove them.

We recommend that you upgrade your pdns packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
