CVE-2024-4030

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.

Summary
  • (es) En Windows, un directorio devuelto por tempfile.mkdtemp() no siempre tendría permisos configurados para restringir la lectura y escritura en el directorio temporal por parte de otros usuarios, sino que normalmente heredaría los permisos correctos de la ubicación predeterminada. Es posible que las configuraciones alternativas o los usuarios sin un directorio de perfil no tengan los permisos previstos. Si no está utilizando Windows o no ha cambiado la ubicación del directorio temporal, esta vulnerabilidad no le afecta. En otras plataformas, el directorio devuelto solo el usuario actual puede leerlo y escribirlo constantemente. Este problema se debió a que Python no admite permisos de Unix en Windows. La solución agrega soporte para Unix “700” para la función mkdir en Windows que utiliza mkdtemp() para garantizar que el directorio recién creado tenga los permisos adecuados.
