fuzz: provide more realistic values to the base58(check) decoders #31917

l0rinc · 2025-02-20T16:23:37Z

This is a follow-up to #30746, expanding coverage by:

restricting every input for the base58 conversions, capping max sizes to 100 instead of 1000 or all available input (suggested by marcofleon in test: cover base[32|58|64] with symmetric roundtrip fuzz (and padding) tests #30746 (comment)) since most actual usage has lengths of e.g. 21, 34, 78.
providing more valid values to the decoder (suggested by maflcko in test: cover base[32|58|64] with symmetric roundtrip fuzz (and padding) tests #30746 (comment)) by randomly providing a random input or a valid encoded one; this also enables unifying the roundtrip tests to a single roundtrip per fuzz.

Concept ACK a63c5c1a8a012b694

I’ve reviewed the changes and have one main observation:

1. Fuzz Test Limitations

Limiting fuzz to the most common sizes makes sense for efficiency. However, if long strings are still expected to be supported, there should be explicit test coverage for them.

I checked the unit tests for Base58 in src/test/base58_tests.cpp, which reads test cases from test/data/base58_encode_decode.json. The longest existing test case appears on line 18, with a hex-encoded string of size 512. Given that this PR removes the long string test from the fuzz tests, it may be beneficial to add a new test case in base58_encode_decode.json to verify behaviour at 1000 characters.

2. Fuzz Test Execution

After static review, I ran the fuzz tests using:

$ cmake --preset=libfuzzer
$ cmake --build build_fuzz -j "$(($(nproc)+1))"

$ FUZZ=base58_encode_decode build_fuzz/src/test/fuzz/fuzz -max_total_time=30 -
$ FUZZ=base58check_encode_decode build_fuzz/src/test/fuzz/fuzz -max_total_time=30
$ FUZZ=base32_encode_decode build_fuzz/src/test/fuzz/fuzz -max_total_time=30 
$ FUZZ=base64_encode_decode build_fuzz/src/test/fuzz/fuzz -max_total_time=30 
$ FUZZ=psbt_base64_decode build_fuzz/src/test/fuzz/fuzz -max_total_time=30

All tests passed successfully within the 30-second run.

src/test/fuzz/base_encode_decode.cpp

        const auto encoded_string{EncodeBase58(decoded)};
        assert(encoded_string == TrimStringView(random_string));
-        assert(encoded_string.empty() || !DecodeBase58(encoded_string, decoded, provider.ConsumeIntegralInRange<int>(0, decoded.size() - 1)));
+        assert(decoded.empty() || !DecodeBase58(encoded_string, decoded, provider.ConsumeIntegralInRange<int>(0, decoded.size() - 1)));


why is the check changed from encoded_string.empty() to decoded.empty() in the first commit - especially if this function is being rewritten in the next commit anyway?

it's the decoded size that determines if the (0, decoded.size() - 1) range makes sense or not - I'm correcting it in the first commit since this was a bug that could cause a fuzz failure (added explanation to commit message).
I'm reordering in the second commit so that we have single roundtrip logic instead of 2 separate ones.

ok, makes sense, but I'd challenge that this is "a bug that could cause a fuzz failure" (otherwise I would've expected this failure to be found by now):
My understanding is that in the relevant special case, both decoded an encoded_string are empty. However, it should be impossible for encoded_string to be empty and decoded non-empty (and vice versa) because of how base58 works.

They seem to cause timeouts: > Issue 397734700: bitcoin-core:base58check_encode_decode: Timeout in base58check_encode_decode The `encoded_string.empty()` check was corrected here to `decoded.empty()` to make sure the `(0, decoded.size() - 1)` range is always valid.

…often In Base58 fuzz the two roundtrips are merged now, the new `decode_input` switches between a completely random input and a valid encoded one, to make sure the decoding passes more often. The `max_ret_len` can also exceed the original length now and is being validated more thoroughly.

(In theory this could be backported to 29.0 to avoid a fuzz timeout there, but it isn't too important, up to the backport maintainer)
