CosmWasm affected by arithmetic overflows
Some mathematical operations in cosmwasm-std use wrapping math instead of
panicking on overflow for very big numbers. This can lead to wrong calculations in contracts
that use these operations.
Affected functions:
Uint{256,512}::pow/Int{256,512}::powInt{256,512}::neg
Affected if overflow-checks = true is not set:
Uint{64,128}::pow/Int{64,128}::powInt{64,128}::neg
