Solidity vulnerabilities

Mar 23, 2018 · Kalra S., Goel S., et al have recently published a research paper on analyzing the safety of smart contracts. They describe the problem of the unchecked send function: “Since Solidity allows only 2300 gas upon a send call, a computation-heavy fallback function at the receiving contract will cause the invoking send to fail. Researchers identified 44 vulnerabilities, 26 attacks and 47 proposed defense ... 'Smart contract programming' and 'Solidity language and toolchain'.Vulnerabilities and bugs that escape recognition persist and remain a concern for developers and enterprises. Preemptive detection of vulnerabilities before program execution is a challenging problem because it is hard to statically characterize a program. Although a vulnerability (such as a buffer overflow) is easy to describe,4-Another important feature is that Solidity supports inline assembly, which enables low-level operations (EVM dialect) that are not supported or allowed by the Solidity language. 5- One low level built-in operation is return that quits the execution context (internal message call) and returns the size and offset in the data area (memory) to the caller.Martin Swende has an excellent blog post describing some quirks of the self-destruct opcode (Quirk #2) ...
