Package        : mbedtls
CVE ID         : CVE-2017-18187 CVE-2018-0487 CVE-2018-0488
Debian Bug     : 890287 890288

Several vulnerabilities were discovered in mbed TLS, a lightweight
crypto and SSL/TLS library, that allowed a remote attacker to either
cause a denial-of-service by application crash, or execute arbitrary
code.

For the stable distribution (stretch), these problems have been fixed in
version 2.4.2-1+deb9u2.

We recommend that you upgrade your mbedtls packages.

For the detailed security status of mbedtls please refer to
its security tracker page at:
