CVE-2024-4030— tempfile.mkdtemp() may be readable and writeable by all users on Windows

tempfile.mkdtemp() may be readable and writeable by all users on Windows

On Windows a directory returned by tempfile.mkdtemp() would not always have permissions set to restrict reading and writing to the temporary directory by other users, instead usually inheriting the correct permissions from the default location. Alternate configurations or users without a profile directory may not have the intended permissions. If you’re not using Windows or haven’t changed the temporary directory location then you aren’t affected by this vulnerability. On other platforms the returned directory is consistently readable and writable only by the current user. This issue was caused by Python not supporting Unix permissions on Windows. The fix adds support for Unix “700” for the mkdir function on Windows which is used by mkdtemp() to ensure the newly created directory has the proper permissions.

N/A

缺省权限不正确

Python 安全漏洞

Python是Python基金会的一套开源的、面向对象的程序设计语言。该语言具有可扩展、支持模块和包、支持多种平台等特点。 python 存在安全漏洞，该漏洞源于 Python 不支持 Windows 上的Unix权限，tempfile.mkdtemp() 返回的目录不会具有限制其他用户读取和写入临时目录。
