There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - CoreDNS is a DNS server written in Go. In versions prior to 1.14.3, the gRPC, QUIC, DoH, and DoH3
    transport implementations incorrectly handle TSIG authentication. For gRPC and QUIC, the server checks
    whether the TSIG key name exists in the configuration but never calls dns.TsigVerify() to validate the
    HMAC. If the key name matches a configured key, the tsigStatus field remains nil and the tsig plugin
    treats the request as successfully authenticated regardless of the MAC value. For DoH and DoH3, the issue
    is more severe: the DoHWriter.TsigStatus() method unconditionally returns nil, and the server never
    inspects the TSIG record at all. Any request containing a TSIG record is treated as authenticated over DoH
    and DoH3, even if the key name is invalid and the MAC is arbitrary. An unauthenticated network attacker
    can exploit this to bypass TSIG-protected functionality such as AXFR/IXFR zone transfers, dynamic DNS
    updates, or other TSIG-gated plugin behavior. The DoH and DoH3 variants have a lower exploitation bar
    because the attacker does not need to know a valid TSIG key name. This issue has been fixed in version
    1.14.3. As a workaround, disable gRPC, QUIC, DoH, and DoH3 listeners where TSIG authentication is
    required, or restrict network-level access to affected transport ports to trusted sources only.
    (CVE-2026-35579)

An update of the coredns package has been released.

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:20703-1 advisory.

    Changes in coredns:

    - Update to version 1.14.3:
      * This release introduces Windows service support, along with full TSIG         verification across DoH, DoH3, QUIC, and gRPC transports, and improved         TSIG propagation and DoH request validation.
      * It also adds optional TLS for the metrics endpoint.
      * Performance and stability are improved through cache prefetching, QUIC         optimizations, and a new max_age option in the forward plugin.
      * Additional updates include enhanced SVCB/HTTPS support, improved zone         transfer behavior, and various DNSSEC, PROXY protocol, and concurrency         fixes.
      * The release is built with Go 1.26.2, which includes security         fixes addressing CVE-2026-32282, CVE-2026-32289, CVE-2026-33810,         CVE-2026-27144, CVE-2026-27143, CVE-2026-32288, CVE-2026-32283,         and CVE-2026-27140, and also includes fixes for CVE-2026-32936,         CVE-2026-33190, CVE-2026-33489, CVE-2026-32934, and CVE-2026-35579.
