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

  - CoreDNS is a DNS server that chains plugins. Starting in version 1.2.0 and prior to version 1.12.4, the
    CoreDNS etcd plugin contains a TTL confusion vulnerability where lease IDs are incorrectly used as TTL
    values, enabling DNS cache pinning attacks. This effectively creates a DoS condition for DNS resolution of
    affected services. The `TTL()` function in `plugin/etcd/etcd.go` incorrectly casts etcd lease IDs (64-bit
    integers) to uint32 and uses them as TTL values. Large lease IDs become very large TTLs when cast to
    uint32. This enables cache pinning attacks. Version 1.12.4 contains a fix for the issue. (CVE-2025-58063)

The version of CBL-Mariner Releases installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-58063 advisory.
