Description

Affected versions of this crate is not panic safe within callback functions stream_callback and stream_finished_callback.

The call to user-provided closure might panic before a mem::forget call, which then causes a use after free that grants attacker to control the callback function pointer.

This allows an attacker to construct an arbitrary code execution .

The flaw was reported by Phosphorus15.
