CVE-2023-39332

CVE-2023-39332 concerns Node.js: certain node:fs path operations permit traversal when paths are provided as non-Buffer Uint8Array objects. The vulnerability contrasts with existing mitigations for string paths and Buffer paths (CVE-2023-30584 and CVE-2023-32004). The issue arises in environments...

CVE-2023-39332

Various node:fs functions allow specifying paths as either strings or Uint8Array objects. In Node.js environments, the Buffer class extends the Uint8Array class. Node.js prevents path traversal through strings see CVE-2023-30584 and Buffer objects see CVE-2023-32004, but not through non-Buffer...

Google Chrome: Integer Overflow when Processing WebAssembly Locals(CVE-2018-6092)

When v8 decodes the locals of a function, it performs a check: if count + typelist-size kV8MaxWasmFunctionLocals decoder-errordecoder-pc - 1, "local count too large"; return false; On a 32-bit platform, this check can be bypassed due to an integer overflow. This allows the number of function loca...
