ELSA-2026-61586-0 - tar security, bug fix, and enhancement update

Type:	SECURITY
Impact:	MODERATE
Release Date:	2026-09-01

Description

[2:1.35-13]
- 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.

[2:1.35-12]
- 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
