CVE-2020-37288
Description
A flaw was found in Vyper. A remote attacker can cause a Denial of Service (DoS) against affected smart contracts by submitting transactions that invoke specific contract functions. Due to incorrect bytecode generation for return statements located inside loops within nested internal calls, the contract triggers an invalid jump destination. This condition causes an unexpected stack underflow that forces transactions to revert, disrupting contract operations.
