CVE-2024-26149

LOW

vyperlang/vyper < 0.3.10 - Memory Buffer Overflow in _abi_decode Array Index Handling

Title source: llm
STIX 2.1

Description

Vyper is a pythonic Smart Contract Language for the ethereum virtual machine. If an excessively large value is specified as the starting index for an array in `_abi_decode`, it can cause the read position to overflow. This results in the decoding of values outside the intended array bounds, potentially leading to exploitations in contracts that use arrays within `_abi_decode`. This vulnerability affects 0.3.10 and earlier versions.
