Package : mbedtls
CVE ID : CVE-2018-0497 CVE-2018-0498
Two vulnerabilities were discovered in mbedtls, a lightweight crypto and
SSL/TLS library which could result in plain text recovery via
side-channel attacks.
For the stable distribution (stretch), these problems have been fixed in
version 2.4.2-1+deb9u3.
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

these updates to your system and frequently asked questions can be
