Upgrade openssl to version 0.10.78 or higher.
Overview
openssl is a bindings for the Rust programming language.
Affected versions of this package are vulnerable to Out-of-bounds Write in the unwrap_key function in the AES key unwrap component. An attacker can trigger a panic and unexpected behavior by supplying an output buffer whose length does not satisfy the asserted relationship to the wrapped input length. The vulnerable length check rejects valid oversized outputs and accepts undersized ones until the unwrap path is exercised, at which point the key unwrap operation fails or aborts when processing attacker-controlled wrapped key material.
