I think the erratum needs an erratum.  Firstly, nonce doesn't mean "number
used once".  Secondly, nonce reuse doesn't just result in a failure of
integrity-protection, it also results in a loss of confidentiality protection.
In other words it leads to total breach of the encryption mode's security,
both properties that it's supposed to provide are no longer present.
