This affects all versions of package ansi-html. If an attacker provides a malicious string, it will get stuck processing the input for an extremely long time.

Setting hosted services 'notaffected.'
Affected package appears in nodejs package-lock.json (and yarn.lock) but does not appear in any source code.
