- →Crafted WebAssembly module with an overflowed local count (LEB128-encoded value 0xffffffff0f) in the function locals section triggers the integer overflow on 32-bit Chrome builds prior to 66.0.3359.117. ↗
- →The overflow occurs in the WebAssembly local-count accumulation check: `(count + type_list->size()) > kV8MaxWasmFunctionLocals`. Monitor for .wasm payloads or inline WebAssembly.Module instantiation with abnormally large local-count fields. ↗
- ·Vulnerability is specific to 32-bit platform builds of Chrome; 64-bit builds are not affected by this integer overflow path. ↗
- ·Exploitation is sandboxed; arbitrary code execution is confined within the Chrome sandbox and would require a sandbox escape for full system compromise. ↗

CVE-2018-4121 The Problems and Promise of WebAssembly - Project Zero
Posted by Natalie Silvanovich, Project Zero
WebAssembly is a format that allows code written in assembly-like instructions to be run from JavaScript. It has recently been implemented in all four major browsers. We reviewed each browser’s WebAssembly implementation and found three vulnerabilities. This blog post gives an overview of the features and attack surface of WebAssembly, as well as the vulnerabilities we found.
##
Building WebAssembly
A number of tools can be used to write WebAssembly code. An important goal of the designers of the format is to be able to compile C and C++ into WebAssembly, and compilers exist to do so. It is likely that other languages will compile into WebAssembly in the future. It is also possible to write WebAssembly in WebAssembly text format which is a d
