Debian DSA-4138-1 : mbedtls - security update

High Nessus Plugin ID 108386


The remote Debian host is missing a security-related update.


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.


Upgrade the mbedtls packages.

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