  "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.\n\nThis happens when the size is a not a multiple of 8 or is negative.\n\nA workaround is to ensure size%8 == 0 \u0026\u0026 size \u003e= 0 yourself before calling NewBitfield or FromBytes.",
