| description: | |
| ReadUvarint and ReadVarint can read an unlimited number of bytes from |
| invalid inputs. |
| |
| Certain invalid inputs to ReadUvarint or ReadVarint can cause these |
| functions to read an unlimited number of bytes from the ByteReader |
| parameter before returning an error. This can lead to processing more |
| input than expected when the caller is reading directly from a |
| network and depends on ReadUvarint or ReadVarint only consuming a |
| small, bounded number of bytes, even from invalid inputs. |
