For the oldstable distribution (stretch), these problems have been fixed in version 2016.11.2+ds-1+deb9u3.

For the stable distribution (buster), these problems have been fixed in version 2018.3.4+dfsg1-6+deb10u1.

We recommend that you upgrade your salt packages.

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