    Summary: stellar-strkey vulnerable to panic in SignedPayload::from_payload

    Details: ### Impact Panic vulnerability when a specially crafted payload is used. This is because of the following calculation: ```rust inner_payload_len + (4 - inner_payload_len % 4) % 4 ``` If `inner_payload_len` is `0xffffffff`, `(4 - inner_payload_len % 4) % 4 = 1` so ```rust inner_payload_len + (4 - inner_payload_len % 4) % 4 = u32::MAX + 1 ``` which overflow. ### Patches Check that `inner_payload_len` is not above 64 which should never be the case. Patched in version 0.0.8 ### Workarounds Sanitize input payload before it is passed to the vulnerable function so that bytes in `payload[32..32+4]` and parsed as a `u32` is not above 64. ### References GitHub issue #58
