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...

SUSE CVE-2026-81634

In NLnet Labs Unbound up to and including 1.26.0, a 255 length query name with a large TCP response can lead to a heap buffer overflow during the RRSet canonicalisation routine. This is caused by missing to add the first owner name into the buffer length check. A malicious actor operating a...

SUSE CVE-2026-81642

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...
