The Huffman repeat mode checker assumed that the CTable was zeroed in the region `[maxSymbolValue + 1, 256)`. This assumption didn't hold for tables built in the dictionaries, because it didn't go through the same codepath. Since this code was originally written, we added a header to the CTable that specifies the `tableLog`. Add `maxSymbolValue` to that header, and check that the table's `maxSymbolValue` is at least the block's `maxSymbolValue`. This solution is cleaner because we write this header for every CTable we build, so it can't be missed in any code path. Credit to OSS-Fuzz |
