CVE-2021-43527

Mozilla

Every applicability statement published about this vulnerability, kept as each source wrote it rather than merged into one verdict. Where sources disagree, both positions are shown.

Does it affect your version?

A statement that names no version covers the whole product, which is not the same as your version falling inside a range. Orderings marked best effort come from schemes with no published comparison algorithm; exact ones follow a published specification.
