SputnikVM, also called evm, is a Rust implementation of Ethereum Virtual Machine. A custom stateful precompile can use the is_static
parameter to determine if the call is executed in a static context (via STATICCALL
), and thus decide if stateful operations should be done. Prior to version 0.36.0, the passed is_static
parameter was incorrect – it was only set to true
if the call came from a direct STATICCALL
opcode. However, once a static call context is entered, it should stay static. The issue only impacts custom precompiles that actually uses is_static
. For those affected, the issue can lead to possible incorrect state transitions. Version 0.36.0 contains a patch. There are no known workarounds.
The code contains a control flow path that does not reflect the algorithm that the path is intended to implement, leading to incorrect behavior any time this path is navigated.
