Affected configurations: geth 1.4.8
Probability: Excessive
Severity: Excessive
Particulars:
An assault vector has been recognized within the freshly launched implementation of the DAO tender fork. The fork enactment code in geth (and different shoppers) permits execution of EVM code as much as the block gasoline restrict with out paying for gasoline. This may decelerate mining and forestall inclusion of reputable transactions.
The tender fork is not going to be enabled if the gasoline restrict of block 1800000 is above 4000000 gasoline (i.e. if the group vote to activate the fork fails). The assault can’t be carried out on this case.
Results on anticipated chain reorganisation depth: None
Proposed short-term workarounds:
- run geth 1.4.7
- run geth 1.4.8 with out the –dao-soft-fork command line choice.
Comply with-up motion:
Out there choices are being thought-about. The group can keep away from any detrimental penalties of the tender fork by voting in opposition to it till a greater answer has been discovered. Observe that, to the most effective of our information, no funds could be retrieved from the affected DAOs till July 14th 2016. There is no such thing as a instant urgency to dam transactions whereas additional proposals are being labored out.
