CVE-2022-39354 Information

Description

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.
