The NAF computation can generate a 1 in the last digit (only) when s = 2^255-1, so someone who manually constructed the value s = 2^255-1 and fed it into a NAF-using computation could generate an incorrect result. Some version of this bug has been present from the beginning of the library, but it has no security content, because the NAF computations are not applied to secret data, and the error occurs only on one value which is not constructed by any client caller. |
