CyberRota Analysis

AI-Generated

The vulnerability affects systems that handle path resolution with relative paths containing parent directory segments, which previously suffered from inefficient string conversions and buffer rewrites, leading to quadratic time complexity and excessive memory usage. The updated method utilizes index-based backtracking, enhancing performance and reducing memory overhead. Organizations that rely on file path resolution in their applications should prioritize this update to improve efficiency and resource management.

Original NVD Description

Previously, resolving relative paths containing parent directory ('..') segments performed string conversions and buffer rewrites on each step, resulting in quadratic time complexity and high memory allocation overhead. Now, path resolution operates on a byte buffer using index-based backtracking for '..' segments, eliminating the quadratic time complexity and significantly reducing memory allocations.
