A BIND resolver encountering an SVCB/HTTPS AliasMode record referencing 14 or more SVCB/HTTPS ServiceMode records may fail to properly deallocate internal resources. If this happens repeatedly, resource exhaustion will eventually prevent the resolver from performing new recursive lookups. This issue affects BIND 9 versions 9.18.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.18.11-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1.

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

  - A BIND resolver encountering an SVCB/HTTPS AliasMode record referencing 14 or more SVCB/HTTPS ServiceMode
    records may fail to properly deallocate internal resources. If this happens repeatedly, resource
    exhaustion will eventually prevent the resolver from performing new recursive lookups. This issue affects
    BIND 9 versions 9.18.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.18.11-S1 through
    9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1. (CVE-2026-81563)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-3137 advisory.

    For a secondary zone with transfers restricted by TSIG, `named` may start to serve the data provided in a     zone transfer before the final message with the TSIG signature arrives. This could allow an attacker that     does not actually possess a valid TSIG signature to send unauthorized zone contents to a secondary server.
    Although no TSIG signature ever arrives, `named` does not rollback to the pre-transfer state. To exploit     the vulnerability, the transfer must be a multi-message TCP IXFR, as described by RFC 8945.This issue     affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.11.3-S1     through 9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1. (CVE-2026-19033)

    An attacker may be able to cause a `named` resolver to abort. The attack requires inducing the victim     resolver to send multiple queries for a DNSSEC-signed zone hosted by an authoritative server under the     control of the attacker. If the auth responds with a particular sequence of crafted answers, and those     answers arrive in a particular order with particular timing, the `named` resolver will encounter a use-     after-free bug, and abort.This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through     9.20.27, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1. (CVE-2026-19662)

    On a resolver configured to use ``dns64``, if an applicable answer from the authoritative server is     malformed in a specific way, the resolver `named` process will exit unexpectedly.This issue affects BIND 9     versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.11.3-S1 through     9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1. (CVE-2026-19666)

    If an attacker-controlled authoritative server can produce a negative answer that is exactly 65536 bytes,     then a flaw in `named` results in a negative cache entry of 0 bytes. When this entry is subsequently read,     `named` aborts.This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0     through 9.21.25, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1. (CVE-2026-19667)

    An inapplicable NSEC record may be accepted by a `named` resolver as proof that no wildcard exists, which     could allow an attacker at the same or an upstream level of the zone name to mask the existence of a     victim's wildcard record.This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through     9.20.27, 9.21.0 through 9.21.25, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1.
    (CVE-2026-19941)

    In a query response, an attacker may send `named` multiple copies of a record that should only exist once     (such as an SOA record). If the RDATA is the same on all the copies, the record is appended to the in-     memory RDATA set, which can cause increased memory usage of the negative cache and possibly lead to other     memory attack vectors.This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.27,     9.21.0 through 9.21.25, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1. (CVE-2026-75029)

    A malformed zone may contain an NS or DNAME node above its origin, which `named` treats as a zone cut. If     an attacker inserts a malformed zone into a BIND authoritative server (e.g., via zone transfer), queries     for names inside the configured zone then lose authoritative status and return an out-of-zone delegation.
    On a server that also provides recursion BIND can follow this locally sourced cut and cache attacker-     supplied data, affecting names outside the configured zone. This situation persists as long as the     malformed zone remains in the zone database.This issue affects BIND 9 versions 9.11.0 through 9.18.50,     9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through     9.20.27-S1. (CVE-2026-78301)

    If a BIND resolver sends a query for a DNSSEC-signed authoritative zone, and the authoritative server     replies with a valid wildcard answer and signed NSEC3 proof, followed by an unsigned NSEC at the same     owner name, it will trigger an unexpected program exit.This issue affects BIND 9 versions 9.11.0 through     9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1     through 9.20.27-S1. (CVE-2026-80274)

    A BIND resolver encountering an SVCB/HTTPS AliasMode record referencing 14 or more SVCB/HTTPS ServiceMode     records may fail to properly deallocate internal resources. If this happens repeatedly, resource     exhaustion will eventually prevent the resolver from performing new recursive lookups.This issue affects     BIND 9 versions 9.18.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.18.11-S1 through     9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1. (CVE-2026-81563)

    If a BIND resolver has cached a tree of SVCB/HTTPS AliasMode records, and is then queried for the root of     that tree, the resolver will spend disproportionate CPU time constructing the response.This issue affects     BIND 9 versions 9.18.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.18.11-S1 through     9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1.

    Package        : bind9     CVE ID         : CVE-2026-19033 CVE-2026-19662 CVE-2026-19666 CVE-2026-19667                      CVE-2026-19668 CVE-2026-75029 CVE-2026-76163 CVE-2026-77119                      CVE-2026-77692 CVE-2026-80274 CVE-2026-81563 CVE-2026-81736

    Several vulnerabilities were discovered in BIND, a DNS server implementation,     which may result in denial of service or cache poisoning.

    For the stable distribution (trixie), these problems have been fixed in     version 1:9.20.29-1~deb13u1.

    We recommend that you upgrade your bind9 packages.

    For the detailed security status of bind9 please refer to     its security tracker page at:

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

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A BIND resolver encountering an SVCB/HTTPS AliasMode record referencing 14 or more SVCB/HTTPS ServiceMode     records may fail to properly deallocate internal resources. If this happens repeatedly, resource     exhaustion will eventually prevent the resolver from performing new recursive lookups. This issue affects     BIND 9 versions 9.18.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.18.11-S1 through     9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1. (CVE-2026-81563)

Note that Nessus relies on the presence of the package as reported by the vendor.
