"The remote openSUSE host is missing one or more security updates.");
  script_set_attribute(attribute:"description", value:
"The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the
openSUSE-SU-2026:21669-1 advisory.

    Changes in wicked:

    - Fix two OOB reads in ni_capture_inspect_udp_header and improve:
      - Reject packets with ip_len < ihl to avoid a size_t underflow of the
        UDP length, which the checksum truncates to uint16_t (bsc#1274627,
        CVE-2026-71401).
      - Set payload_len to the remaining payload, not ip_len, which over-read
        the DHCP option walker by ihl + 8 bytes past the buffer (bsc#1274627,
        CVE-2026-71402).
      - Avoid checksumming packets that fail the length/protocol checks and
        tidy up the debug messages (bsc#1274627).
      - Fix underflow check in ni_dhcp4_option_next to handle option code
        and length separately as the END and PAD options don't have length
        (bsc#1274627).
