Overview

openssl is a bindings for the Rust programming language.

Affected versions of this package are vulnerable to Improper Handling of Length Parameter Inconsistency through the PSK and cookie generation callback trampolines in the Rust bindings. An attacker can cause the library to serialize adjacent memory into a TLS PSK exchange or a DTLS HelloVerifyRequest by supplying a callback that returns a length greater than the provided slice. This leaks bytes past the end of the PSK or cookie buffer to the network peer during handshake processing, exposing process memory to a remote client.
