Description

A flaw was found in BusyBox. When extracting files using the cpio utility with path traversal protection enabled, hardlink target paths are not properly sanitized. By tricking a user or automated process into extracting a crafted archive, an attacker can create hardlinks that point to files outside the intended extraction directory. This issue may allow an attacker to modify or overwrite arbitrary files outside the target directory during subsequent extraction operations.
