> A server or application embedding this library keys a _HashMap_/_HashSet_ by
> _Dn_ (entry caches, group-membership sets, subscription maps — *ApacheDS* and
> many consumers do); an attacker injecting many distinct *DNs* (adds, binds,
> processed search results) makes every key land in one bucket, driving *CPU*
> exhaustion via quadratic normalizer-heavy comparisons.
