Summary
[2:1.30-13]
- Backport upstream fix for CVE-2026-5704 (file injection hidden from -t)
- Fix --one-top-level with absolute path (broken by the CVE-2025-45582 fix)
Also fixes CVE-2026-18508 (escape from --one-top-level via hardlinks).
- Upstream fix for build with libacl 2.4.0
- Backport upstream patches for CVE-2026-18477, fixes a bug
where incremental restore with cyclic renames between backups
may create a temporary directory at an archive-controlled path
outside the extraction tree.
The fix for CVE-2025-45582 already prevents exploiting
this problem, so it is more a correctness and hardening change.
[2:1.30-12]

Tar: tar: hidden file injection via crafted archives
A flaw was found in tar. A remote attacker could exploit this vulnerability by crafting a malicious archive, leading to hidden file injection with fully attacker-controlled content. This bypasses pre-extraction inspection mechanisms, potentially allowing an a…

Tar: tar: toctou in incremental dumpdir 'x' rename handling allows restore path escape
A TOCTOU (Time-of-Check Time-of-Use) vulnerability in GNU tar's incremental dumpdir 'X' rename handling allows a local attacker with write access to a directory being backed up to influence the restore process if the attacker has access to the system where th…

Tar: tar: --one-top-level hardlink targets not confined to top-level directory enabling arbitrary file overwrite
A flaw was found in GNU tar. When extracting an archive with the --one-top-level option, hardlink targets are not confined to the designated top-level directory and may resolve relative to the extraction working directory. A crafted archive can create hardlin…
