For Debian 10 buster, these problems have been fixed in version 2.16.9-0~deb10u1.

We recommend that you upgrade your mbedtls packages.

For the detailed security status of mbedtls please refer to its security tracker page at: [link moved to references]

Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
