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 mushy 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 could decelerate mining and forestall inclusion of professional transactions.
The mushy fork won’t 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:
Accessible choices are being thought-about. The group can keep away from any destructive penalties of the mushy fork by voting in opposition to it till a greater resolution has been discovered. Notice that, to the very best of our information, no funds will be retrieved from the affected DAOs till July 14th 2016. There isn’t a fast urgency to dam transactions whereas additional proposals are being labored out.
