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

  - CoreDNS is a DNS server that chains plugins. In versions prior to 1.14.3, the DNS-over-QUIC (DoQ) server
    can be driven into unbounded goroutine and memory growth by a remote client that opens many QUIC streams
    and sends only 1 byte per stream. When the worker pool is full, CoreDNS still spawns a goroutine per
    accepted stream to wait for a worker token. Additionally, active workers block indefinitely in
    io.ReadFull() with no per-stream read deadline, allowing an attacker to pin all workers by sending a
    single byte so the read blocks waiting for the second byte of the DoQ length prefix. This enables an
    unauthenticated remote attacker to cause memory exhaustion and OOM-kill. This issue has been fixed in
    version 1.14.3. No known workarounds exist. (CVE-2026-32934)

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.
