Description

The KeyValueReader type in affected versions of this crate set up an uninitialized memory buffer and passed them to be read in to a user-provided Read instance.

The Read instance could read uninitialized memory and cause undefined behavior and miscompilations.

This issue was fixed in commit dd59b30 by zero-initializing the buffers before passing them.
