Vyper 安全漏洞

Vyper is a Pythonic smart contract language for EVM open sourced by vyperlang. A security vulnerability exists in Vyper 0.4.0 and earlier versions, which stems from the compiler failing to check the success flag of a call when using pre-compiled EcRecover and Identity, which could lead to incorre...

CVE-2024-43366 zkvyper ignored loop range bounds

zkvyper is a Vyper compiler. Starting in version 1.3.12 and prior to version 1.5.3, since LLL IR has no Turing-incompletness restrictions, it is compiled to a loop with a much more late exit condition. It leads to a loss of funds or other unwanted behavior if the loop body contains it. However,...
