Debian Bug : 941265 963159 972806 1002631

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.

For the detailed security status of mbedtls please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/mbedtls

Further information about Debian LTS security advisories, how to apply
these updates to your system and frequently asked questions can be
