    Summary: Denial of service via malformed size parameters in github.com/ipfs/go-bitfield

    Details: When feeding untrusted user input into the size parameter of NewBitfield and FromBytes functions, an attacker can trigger panics. This happens when the size is a not a multiple of 8 or is negative. A workaround is to ensure size%8 == 0 && size >= 0 yourself before calling NewBitfield or FromBytes.
