#javascript#cheerp#cheerpx#cpp#lwip#repl#tailscale#vm#wasm#webassembly#webvm#xterm_js WebVM lets you run a full Linux system directly in your web browser without needing a server. It uses a special engine called CheerpX to safely run unmodified Linux programs by converting x86 code to WebAssembly. You get a real Debian Linux environment with many tools, and it supports networking through Tailscale VPN, so your browser VM can connect securely to the internet. You can also customize and deploy your own WebVM easily using GitHub, making it great for development, testing, or learning Linux without installing anything. This means you can have a powerful, private Linux machine anytime, anywhere, just in your browser[1][2][3]. https://github.com/leaningtech/webvm

CPython zipfile 模块高危漏洞 CVE-2024-8088 CPython 的 zipfile 模块存在一个高危漏洞，编号为 CVE-2024-8088。该漏洞会导致在处理恶意构造的 zip 档案时，程序陷入无限循环。具体来说，当使用 zipfile.Path 类及其方法（如 namelist()`、`iterdir()`、`extractall() 等）遍历 zip 档案条目名称时，可能会触发无限循环。此漏洞的根本原因在于 zipfile._path._ancestry() 方法中的路径处理不当。具体来说，代码中的 path.rstrip(posixpath.sep) 和 while 循环条件未正确处理路径，导致无限循环。例如，`posixpath.split("//") 返回 ("//", "")，而 "//" != posixpath.sep` 导致循环无法退出。该漏洞已被修复，建议更新 CPython 并加强输入验证，以防止潜在的拒绝服务攻击。原文链接：https://www.openwall.com/lists/oss-security/2024/08/22/1https://www.openwall.com/lists/oss-security/2024/08/22/4 标签：#CPython#漏洞#zipfile#无限循环 #AIGC
