CVE-2024-24561

Vyper is a pythonic Smart Contract Language for the ethereum virtual machine. In versions 0.3.10 and earlier, the bounds check for slices does not account for the ability for start + length to overflow when the values aren't literals. If a slice function uses a non-literal argument for the start ...

CVE-2024-32649

Vyper is a pythonic Smart Contract Language for the Ethereum virtual machine. In versions 0.3.10 and prior, using the sqrt builtin can result in double eval vulnerability when the argument has side-effects. It can be seen that the buildIR function of the sqrt builtin doesn't cache the argument to...
