### GitHub Vulnerability Alerts

####
[GHSA-cq8v-f236-94qc](https://redirect.github.com/rust-random/rand/pull/1763)

It has been reported (by @&#8203;lopopolo) that the `rand` library is
[unsound](https://rust-lang.github.io/unsafe-code-guidelines/glossary.html#soundness-of-code--of-a-library)
(i.e. that safe code using the public API can cause Undefined Behaviour)
when all the following conditions are met:

- The `log` and `thread_rng` features are enabled
- A [custom
logger](https://docs.rs/log/latest/log/#implementing-a-logger) is
defined
- The custom logger accesses `rand::rng()` (previously
`rand::thread_rng()`) and calls any `TryRng` (previously `RngCore`)
methods on `ThreadRng`
- The `ThreadRng` (attempts to) reseed while called from the custom
logger (this happens every 64 kB of generated data)
- Trace-level logging is enabled or warn-level logging is enabled and
the random source (the `getrandom` crate) is unable to provide a new
seed

`TryRng` (previously `RngCore`) methods for `ThreadRng` use `unsafe`
code to cast `*mut BlockRng<ReseedingCore>` to `&mut
BlockRng<ReseedingCore>`. When all the above conditions are met this
results in an aliased mutable reference, violating the Stacked Borrows
rules. Miri is able to detect this violation in sample code. Since
construction of [aliased mutable references is Undefined
Behaviour](https://doc.rust-lang.org/stable/nomicon/references.html),
the behaviour of optimized builds is hard to predict.

Affected versions of `rand` are `>= 0.7, < 0.9.3` and `0.10.0`.
