Abstract: Implementation bug within the go consumer could result in invalid state
Affected consumer variations: Newest (unpatched) variations of Go consumer; v1.1.2, v1.0.4 tags and develop, grasp branches earlier than September 9.
Chance: Low
Severity: Excessive
Influence: Excessive
Particulars: Go ethereum consumer doesn’t accurately restore state of execution surroundings when a transaction goes out-of-gas if – inside the identical block – a contract was suicided. This could lead to an invalid copy operation of the state object; flagging the contract as not deleted. This operation would trigger a consensus challenge between the opposite implementations.
Results on anticipated chain reorganisation depth: none
Remedial motion taken by Ethereum: Provision of hotfixes as under.
Proposed short-term workaround: Use Python or C++ consumer
If utilizing the PPA: sudo apt-get replace then sudo apt-get improve
If utilizing brew: brew replace then brew reinstall ethereum
If utilizing a home windows binary: obtain the up to date binary from https://github.com/ethereum/go-ethereum/releases/tag/v1.1.3
