This allowed an attacker providing maliciously crafted input to perform code execution, or read arbitrary files on the server.

For the oldstable distribution (stretch), these problems have been fixed in version 2.8.6-1+deb9u6.

For the stable distribution (buster), these problems have been fixed in version 2.9.8-3+deb10u1.

We recommend that you upgrade your jackson-databind packages.

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