Summary

Ward Beullens found a practical key-recovery attack against Rainbow. The level I parametersets are removed from liboqs starting from version `0.7.2`. Find the scientific details in [Breaking Rainbow Takes a Weekend on a Laptop](https://eprint.iacr.org/2022/214).

This means all the `oqs::sig::Algorithm::RainbowI*` variants are insecure.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
