-description: |
-    Certain invalid inputs to ReadUvarint or ReadVarint could cause those
-    functions to read an unlimited number of bytes from the ByteReader argument
-    before returning an error. This could lead to processing more input than
-    expected when the caller is reading directly from a network and depends on
-    ReadUvarint and ReadVarint only consuming a small, bounded number of bytes,
-    even from invalid inputs.
-
-    With the update, ReadUvarint and ReadVarint now always return after consuming
-    a bounded number of bytes (specifically, MaxVarintLen64, which is 10). The
-    result being returned has not changed; the functions merely detect and return
-    some errors without reading as much input.
