Overview

nanorand is an A tiny, fast, zero-dep library for random number generation.

Affected versions of this package are vulnerable to NULL Pointer Dereference due to the implementation of tls_rand and TlsWyRand . TlsWyRand's implementation of Deref unconditionally dereferences a raw pointer, and returns multiple mutable references to the same object.
