Fixes a critical heap buffer overflow in nginx's map directive regex handling (CVSS 9.2). The vulnerable range is 0.9.6 through 1.31.2; this bumps the 5.0-9.1.1 branch's nginx package to the patched 1.30.4 stable release. The six CVE backport patches (CVE-2025-53859, CVE-2026-27654, CVE-2026-32647, CVE-2026-27651, CVE-2026-27784, CVE-2026-1642) previously applied on top of 1.26.3 are dropped, as all six fixes are included upstream in 1.30.4.

CVE-2026-42533, a critical heap buffer overflow (CVSS 9.2) in nginx's
map directive regex handling.
Changes
CVE-2026-32647, CVE-2026-27651, CVE-2026-27784, CVE-2026-1642) that
were applied on top of 1.26.3 — all six are included upstream in
