GHSA-5824-CM3X-3C38 Vyper has incorrectly allocated named re-entrancy locks

Impact In versions 0.2.15, 0.2.16 and 0.3.0, named re-entrancy locks are allocated incorrectly. Each function using a named re-entrancy lock gets a unique lock regardless of the key, allowing cross-function re-entrancy in contracts compiled with the susceptible versions. A specific set of...

Incorrect Re-Entrancy Lock Allocation

vyper is vulnerable to Incorrect Re-Entrancy Lock Allocation. The allocation of named re-entrancy locks is flawed, which makes cross-function re-entrancy possible in contracts, because each function employing a named re-entrancy lock receives a distinct lock independent of the key under a specifi...
