Rootstock Labs: Crafted smart contract can take 1.5 minutes to execute due to inefficient CODESIZE implementation

The crafted smart contract can take 1.5 minutes to execute due to an inefficient implementation of the CODESIZE operation in the VM. The issue was caused by the VM.doCODESIZE method, which retrieved the entire code array instead of just the code length. This behavior could be exploited to transfe...
