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.

Weakness

The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.

Affected Software

Name Vendor Start Version End Version
Tinydtls Eclipse * 0.8.2 (including)
Tinydtls Eclipse 0.9-rc1 (including) 0.9-rc1 (including)
