unbound: Unbound: Heap buffer overflow and possible Remote Code Execution when digesting DNSKEY

A flaw was found in Unbound's DNSSEC validator. A remote attacker can exploit this vulnerability by controlling a malicious zone and sending a specially crafted DNSKEY record. This can lead to a heap buffer overflow, potentially resulting in a denial of service or remote code execution...

A flaw was found in Unbound. This vulnerability allows a remote attacker to cause a heap buffer overflow during the processing of DNSSEC responses. By sending a specially crafted DNSSEC response, a malicious server or an attacker tampering with network traffic can trigger this flaw. This could le...

SUSE CVE-2026-19662

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, a...

SUSE CVE-2026-19668

A BIND recursive resolver may experience excessive resource consumption if it encounters large numbers of a particular kind of invalid DNSSEC record. Default limits on "max-records-per-type" and "max-types-per-name" help mitigate the exposure. This issue affects BIND 9 versions 9.11.0 through...

SUSE CVE-2026-80274

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...
