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