maliciously crafted zone (unbounded NSEC3 iterations when validating referrals to unsigned delegations)\n     - CVE-2026-1519\n   * Build the lib/dns \"gen\" host tool with large-file support to fix an\n     armel FTBFS: \"gen\" scans the rdata directories with a non-LFS readdir(),\n     which aborts with EOVERFLOW on 64-bit inodes/offsets on 32-bit\n     architectures.  next_file() in lib/dns/gen-unix.h treats the resulting\n     NULL as end-of-directory, so the scan was silently truncated and \"gen\"\n     emitted an incomplete include/dns/rdatastruct.h.\n     -
