GHSA-w7j2-35mf-95p7 Incorrect check on buffer length in rand_core

• crates.io rand_core: >= 0.6.0, < 0.6.2 → fixed in 0.6.2

An issue was discovered in the rand_core crate before 0.6.2 for Rust. Because `read_u32_into` and `read_u64_into` mishandle certain buffer-length checks, a random number generator may be seeded with too little data. The vulnerability was introduced in v0.6.0. The advisory doesn't apply to earlier minor version numbers.
