What is Heartbleed in TLS?
Heartbleed. It results from improper input validation (due to a missing bounds check) in the implementation of the TLS heartbeat extension. Thus, the bug’s name derives from heartbeat. The vulnerability is classified as a buffer over-read, a situation where more data can be read than should be allowed.
Could Heartbleed have been prevented?
According to Wheeler, the most efficient technique which could have prevented Heartbleed is a test suite thoroughly performing robustness testing, i.e. testing that invalid inputs cause failures rather than successes. Wheeler highlights that a single general-purpose test suite could serve as a base for all TLS implementations.
