Multiple security vulnerabilities have been discovered in mbedtls, a
lightweight crypto and SSL/TLS library, which may allow attackers to obtain
sensitive information like the RSA private key or cause a denial of service
(application or server crash).

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

We recommend that you upgrade your mbedtls packages.
