Linux Vulnerability Repair Library with Isolated Runtime Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The diversity of Linux distributions makes it difficult to apply traditional vulnerability repair methods effectively across different distributions.
Innovation Solution
A data processing method and apparatus that involves loading a target loading and invasion machine into a first memory space of a Linux operating system, creating a second memory space with an isolated runtime environment, and using a vulnerability repair library to perform repairs within this space, allowing for vulnerability repairs across various distributions without requiring separate compilations for each.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional vulnerability repair methods are used, then they work for traditional IT security field, but they cannot be applied to diverse Linux distributions
Solution Approach 1:
The patent introduces a binary translation layer as an intermediary between the original binary code and the target Linux distribution. This translation layer converts binary code from one Linux distribution to another, enabling vulnerability repair libraries compiled for one distribution to be applied to other distributions without recompilation.
Solution Approach 2:
The vulnerability repair library is designed with universal applicability across multiple Linux distributions. By using binary translation technology, a single repair library can serve multiple distribution types (Ubuntu, CentOS, Debian, etc.), eliminating the need to create separate repair libraries for each distribution.
2Manufacturing precision
If separate binary code compilations are performed for each Linux distribution, then vulnerability repairs can be accurate for each distribution, but the compilation complexity and time increase significantly
Solution Approach 1:
The patent performs preliminary binary translation to generate a universal vulnerability repair library that can be applied to multiple Linux distributions. This preliminary action eliminates the need for repeated compilations for each distribution, significantly reducing compilation time while maintaining repair accuracy through the translation layer.
Solution Approach 2:
Instead of compiling separate binary codes for each distribution, the patent creates a copied and translated version of the vulnerability repair library that can be universally applied. The binary translation process generates a portable repair library that preserves the accuracy of distribution-specific repairs while avoiding repeated compilation work.
3Device complexity
If a unified vulnerability repair approach is used across Linux distributions, then compilation complexity is reduced, but compatibility with different distributions may be compromised
Solution Approach 1:
The binary translation layer serves as a compatibility intermediary that ensures unified vulnerability repair approaches work correctly across different Linux distributions. It translates binary code to maintain compatibility with distribution-specific system calls and libraries, preserving reliability while enabling a unified repair process.
Data Source
AI summary
A data processing method, applied to a target device in which a Linux operating system is running. A first program is deployed in the Linux operating system. The method includes: loading a target loading and invasion machine into a first memory space of the first program, and acquiring a vulnerability repair library for the first program through the target loading and invasion machine; creating, in the first memory space, a second memory space for the target loading and invasion machine, and configuring a second runtime environment isolated from a first runtime environment of the first program; and loading the vulnerability repair library in the second memory space based on the second runtime environment, and performing a vulnerability repair on the first program by using the vulnerability repair library.
