For the oldstable distribution (jessie), this problem has been fixed in version 0.0.9+deb8u1.

For the stable distribution (stretch), this problem has been fixed in version 0.0.9+deb9u1.

We recommend that you upgrade your sensible-utils packages.

For the detailed security status of sensible-utils please refer to its security tracker page at: [link moved to references]");
