Bug Solutions

I launched an ERC20 contract via the Open Zeppelin a few months ago. Recently, there was a yellow triangle with an error by the contract on Etherscan that said there was a medium security vulnerability. The Bug Name is: AbiReencodingHeadOverflowWithStaticArrayCleanup. The problem I am running into is I have no idea whether this is solvable or how to proceed. The documentation for the bug is detailed at level of technical depth far beyond my knowledge base. As is this article on the bug, and I am not sure whether there is any recommended or necessary action for fixing it. Any advice or suggestions would be greatly appreciated. Thanks!

Hi,
This seems like a question for the etherscan team, or you could include more details, like your contract, or a link to its etherscan page.

Hi @JulissaDantes thanks for the reply. Sure, here is the contract on Etherscan. The reason I asked here, rather than Etherscan is because I used the Open Zepplin Wizard to create the contract. So, if there is a bug in the contract, it may also apply to other contracts launched with the Wizard software.

I'm having the same bug notification name, AbiReencodingHeadOverflowWithStaticArrayCleanup, did you find more about that?

Hi - no. I haven't found out anything more about this bug. It seems like a potential bug with the Open Zeppelin ERC-20 contract, but I have no idea where to start in resolving it. I'm not sure under what circumstances or whether the bug can be exploited either.

Just wanted to follow up on this. I still haven't found a fix for this. I found another contract with the same bug.

This post focuses on the first (medium-severity) issue, however it seems this might be a product of needed upgrades for the Open Zepplin contract that are causing several small inefficiencies. If anyone has any thoughts or suggestions - I'd sincerely appreciate your time. Thanks!
