For the oldstable distribution (buster), this problem has been fixed in version 2018.3.4+dfsg1-6+deb10u3.

For the stable distribution (bullseye), this problem has been fixed in version 3002.6+dfsg1-4+deb11u1.

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]");
