"The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the
openSUSE-SU-2026:21748-1 advisory.

    Security issues fixed:

    - CVE-2026-68742: insufficient validation in the NSS responder can lead to an out-of-bounds read and a
    process crash
      when a crafted GETHOSTBYADDR request is sent to the NSS responder socket (bsc#1273922).
    - CVE-2026-68743: insufficient validation in the PAM responder can lead to an out-of-bounds read and a
    process crash
      when a crafted protocol v1 request is processed (bsc#1273925).
    - CVE-2026-68744: improper memory management in the NSS responder can lead to uninitialized heap memory
    disclosure
      from the `sssd_nss` process (bsc#1273924).

    Other updates and bugfixes:

    - Add `systemd-tmpfiles` configuration file to populate `/var/lib/sss` with the correct permissions on
    transactional
      servers (bsc#1274748).

Tenable has extracted the preceding description block directly from the SUSE security advisory.
