A flaw was found in BusyBox. When extracting an archive, the tar utility improperly resolves deferred hardlink targets across symbolic links pointing outside the intended extraction directory. An attacker could provide a specially crafted archive that links to sensitive files outside the extraction tree, allowing subsequent extraction operations to overwrite arbitrary files on the system.
