- 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:
inner_payload_len + (4 - inner_payload_len % 4) % 4If
inner_payload_lenis0xffffffff,(4 - inner_payload_len % 4) % 4 = 1soinner_payload_len + (4 - inner_payload_len % 4) % 4 = u32::MAX + 1which overflow.
Patches
Check that
inner_payload_lenis not above 64 which should never be the case. Patched in version 0.0.8Workarounds
Sanitize input payload before it is passed to the vulnerable function so that bytes in
payload[32..32+4]and parsed as au32is not above 64.References
