nanoid vulnerabilities

nanoid prior to versions 3.3.12 and 5.1.11 has a vulnerability in the nanoid(size) function that coerces the size parameter to a signed 32-bit integer, potentially corrupting the CSPRNG state and generating deterministic identifiers.

The nanoid (Nano ID) library before versions 3.3.16 and 5.1.16 contains an infinite loop in the customAlphabet and nanoid functions of its non-secure module. When given a negative size, the loop counter is decremented from a negative value and never reaches its termination condition, hanging the calling thread.

In the nanoid (Nano ID) library before version 5.1.6, there is an infinite loop in the customAlphabet and customRandom functions. When these functions are configured with a size of 0, the internal generation loop never satisfies its exit condition and spins indefinitely, hanging the calling thread.
