Security Vulnerabilities

cosmwasm-std: Arithmetic overflows in cosmwasm-std

RUSTSEC-2024-0338

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}::pow
  • Int{256,512}::neg

Affected if overflow-checks = true is not set:

  • Uint{64,128}::pow / Int{64,128}::pow
  • Int{64,128}::neg
