Tinydtls Security Vulnerabilities - February

CVE-2017-7243

Eclipse tinydtls 0.8.2 for Eclipse IoT allows remote attackers to cause a denial of service (DTLS peer crash) by sending a "Change cipher spec" packet without pre-handshake.

CVE-2021-34430

Eclipse TinyDTLS through 0.9-rc1 relies on the rand function in the C library, which makes it easier for remote attackers to compute the master key and then decrypt DTLS traffic.
