CVE-2026-77955

A flaw was found in Unbound. This vulnerability affects ZONEMD configured zones that are located below a trust anchor, allowing tampered zone contents to be served or stored to disk before integrity checks are completed. This occurs due to the asynchronous resolution of DS/DNSKEY records, which...

CVE-2026-81642 Heap buffer overflow and possible Remote Code Execution when digesting DNSKEY

In NLnet Labs Unbound up to and including 1.26.0, a vulnerability was found in the DNSSEC validator that enables denial of service and possible remote code execution as a result of digesting DNSKEYs. A DNSKEY with an owner compression pointer to its own RDATA can overflow the digest buffer. Remot...

NewStart CGSL MAIN 7.02 : bind Multiple Vulnerabilities (NS-SA-2026-0110)

The remote NewStart CGSL host, running version MAIN 7.02, has bind packages installed that are affected by multiple vulnerabilities: - Querying for records within a specially crafted zone containing certain malformed DNSKEY records can lead to CPU exhaustion. This issue affects BIND 9 versions...

Important: bind

Issue Overview: BIND may accept incorrect child-zone NSEC3 records as valid, which could allow an attacker to forge authenticated NXDOMAIN responses. This issue affects BIND 9 versions 9.18.0 through 9.18.50, 9.20.0 through 9.20.24, 9.21.0 through 9.21.23, 9.11.3-S1 through 9.18.50-S1, and...

Linux Distros Unpatched Vulnerability : CVE-2026-10822

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - If BIND encounters a particular invalid data structure in a DNS record, it will accept the invalid data, and may subsequently abort and exit. BIND will first ne...

CVE-2026-10822

If BIND encounters a particular invalid data structure in a DNS record, it will accept the invalid data, and may subsequently abort and exit. BIND will first need to store a DNS record for a key KEY, DNSKEY, etc.. That key must specify a PRIVATEDNS algorithm 253, and in the algorithm identifier,...

USN-8542-1: Dnsmasq vulnerabilities

Yiwei Hou discovered that Dnsmasq incorrectly handled logging of DS or DNSKEY. A remote attacker could possibly use this issue to cause a denial of service. CVE-2026-12725 It was discovered that Dnsmasq incorrectly validated the length of fixed-length DNS record fields when parsing NS section...

CVE-2026-12725

A heap-based buffer overflow was found in dnsmasq. When DNSSEC validation and query logging are both enabled, logging of DS or DNSKEY replies containing unsupported algorithm or digest types can cause dnsmasq to write past the end of an internal logging buffer. A remote attacker able to supply su...
