impl `FromMdbValue` for bool is unsound

The implementation of FromMdbValue have several unsoundness issues. First of all, it allows to reinterpret arbitrary bytes as a bool and could make undefined behavior happen with safe function. Secondly, it allows transmuting pointer without taking memory layout into consideration. The details of...

RUSTSEC-2021-0022 Use-after-free in `subscript_next` and `subscript_prev` wrappers

Affected versions of this crate had an unsound implementation which could pass a pointer to freed memory to ydbsubscriptnextst and ydbsubscriptprevst if the variable and subscripts did not have enough memory allocated on the first call to hold the next variable in the database. For example, the...
