For the oldstable distribution (bullseye), this problem has been fixed in version 4.2.1-1+deb11u1.

For the stable distribution (bookworm), this problem has been fixed in version 4.2.1-3+deb12u1.

We recommend that you upgrade your node-browserify-sign packages.

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