CVE-2026-124745Busybox: tar deferred hardlink target resolved through a deferred symlink escapes the extraction directory

Red Hat Red Hat Enterprise Linux 6; Red Hat Red Hat Hardened Images Veröffentlicht: 2026-11-11 15:29 (vor 58 Minuten)

Beschreibung

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.
