CVE-2024-24563 Vyper array negative index vulnerability

Vyper is a Pythonic Smart Contract Language for the Ethereum Virtual Machine. Arrays can be keyed by a signed integer, while they are defined for unsigned integers only. The typechecker doesn't throw when spotting the usage of an int as an index for an array. The typechecker allows the usage of...

Vyper Input Validation Error Vulnerability

Vyper is the Pythonic smart contract language for EVM. An input validation error vulnerability exists in Vyper 0.3.10 and earlier versions, which stems from a type checker that allows the use of signed integers as the index of an array, potentially resulting in a denial of service...

Improper Validation

vyper is vulnerable to Improper Validation. The vulnerability is caused due to a miscalculation in stack management during the compilation of the sha364 operation in the IR. This could allow an attacker to manipulate the input and exploit the error in stack management during compilation...

CVE-2024-24559
