The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2807 advisory.

    CVE-2021-25219 Kishore Kumar Kothapalli discovered that the lame server cache in BIND, a DNS server     implementation, can be abused by an attacker to significantly degrade resolver performance, resulting in     denial of service (large delays for responses for client queries and DNS timeouts on client hosts).
    CVE-2018-5740 deny-answer-aliases is a little-used feature intended to help recursive server operators     protect end users against DNS rebinding attacks, a potential method of circumventing the security model     used by client browsers. However, a defect in this feature makes it easy, when the feature is in use, to     experience an assertion failure in name.c. For Debian 9 stretch, these problems have been fixed in version     1:9.10.3.dfsg.P4-12.3+deb9u10. We recommend that you upgrade your bind9 packages.
