CVE-2020-37287 Vyper before 0.2.6 Call Stack Corruption via Complex Type Function Arguments

Vyper before 0.2.6 contains a call stack corruption vulnerability that causes incorrect function outputs when complex types with non-base members are passed as arguments. Contracts passing multi-dimensional arrays or structs to internal or external functions receive corrupted values because the...

CVE-2020-37287

Vyper versions prior to 0.2.6 are susceptible to a call stack corruption vulnerability. The root cause is an incorrect assumption by the compiler that each subtype size is 32, which occurs when complex types with non-base members are passed as function arguments. This flaw leads to corrupted func...
