  • SECURITY UPDATE: CN/DN fallback not precluded by oversized SAN
    • debian/patches/CVE-2026-42013.patch: keep the CN (hostname) and DN-email fallbacks disabled when a subject alternative name is oversized instead of silently ignoring it, per RFC 6125 6.4.4, in lib/x509/hostname-verify.c and lib/x509/email-verify.c.
