Details

IPFS go-bitfield vulnerable to DoS via malformed size arguments ### Impact When feeding untrusted user input into the size parameter of `NewBitfield` and `FromBytes` functions, an attacker can trigger `panic`s. This happen when the `size` is a not a multiple of `8` or is negative. There were already a note in the `NewBitfield` documentation: > ``` > Panics if size is not a multiple of 8. > ```` But it incomplete and missing from `FromBytes`'s documentation. This has been replaced by returning an `(Bitfield, error)` and returning a non nil error if the size is wrong. ### Patches - https://github.com/ipfs/go-bitfield/commit/5e1d256fe043fc4163343ccca83862c69c52e579 ### Workarounds - Ensure `size%8 == 0 && size >= 0` yourself before calling `NewBitfield` or `FromBytes` ### References - https://github.com/ipfs/go-unixfs/security/advisories/GHSA-q264-w97q-q778
