CVE-2024-27934— Deno 安全漏洞

*const c_void / ExternalPointer unsoundness leading to use-after-free

Deno is a JavaScript, TypeScript, and WebAssembly runtime. Starting in version 1.36.2 and prior to version 1.40.3, use of inherently unsafe `*const c_void` and `ExternalPointer` leads to use-after-free access of the underlying structure, resulting in arbitrary code execution. Use of inherently unsafe `*const c_void` and `ExternalPointer` leads to use-after-free access of the underlying structure, which is exploitable by an attacker controlling the code executed inside a Deno runtime to obtain arbitrary code execution on the host machine regardless of permissions. This bug is known to be exploitable for both `*const c_void` and `ExternalPointer` implementations. Version 1.40.3 fixes this issue.

释放后使用

Deno 安全漏洞

Deno是开源的一个简单、现代且安全的JavaScript和 TypeScript运行环境。它使用 V8 并使用 Rust 构建。 Deno 1.36.2 到 1.40.3版本存在安全漏洞，该漏洞源于const c_void、ExternalPointer 不安全，导致释放后重用，从而导致任意代码执行。
