When verifying a certificate chain containing excluded DNS constraints, these constraints are not correctly applied to wildcard DNS SANs which use a different case than the constraint. This only affects validation of otherwise trusted certificate chains, issued by a root CA in the...

CVE-2026-33810 Case-sensitive excludedSubtrees name constraints cause Auth Bypass in crypto/x509

When verifying a certificate chain containing excluded DNS constraints, these constraints are not correctly applied to wildcard DNS SANs which use a different case than the constraint. This only affects validation of otherwise trusted certificate chains, issued by a root CA in the...

Google Go 安全漏洞

Google Go is a static, strongly typed, compiled, concurrent programming language with garbage collection features from the American company Google. There is a security vulnerability in Google Go, which stems from the incorrect application of DNS constraints during certificate chain verification...

bind: BIND: Unauthorized access due to use-after-return vulnerability in DNS query handling

A flaw was found in BIND, specifically in the named server's handling of DNS queries signed with SIG0. A remote attacker could exploit this use-after-return vulnerability by sending a specially-crafted DNS request. This could cause an Access Control List ACL to improperly match an IP address,...

bind: Cache poisoning attacks with unsolicited RRs

A vulnerability exists in BIND’s DNS resolver logic that makes it overly permissive when accepting resource records RRs in responses. Under certain conditions, this flaw allows attackers to inject unsolicited or forged DNS records into the cache. This can be exploited to poison the resolver cache...

bind: BIND: Denial of Service via maliciously crafted DNSSEC-validated zone

A flaw was found in BIND. A remote attacker could exploit this vulnerability by sending a maliciously crafted DNSSEC-validated zone to a BIND resolver. This could cause the resolver to consume excessive CPU resources, leading to a denial of service DoS for legitimate users...

CVE-2026-35406

Aardvark-dns is an authoritative dns server for A/AAAA container records. From 1.16.0 to 1.17.0, a truncated TCP DNS query followed by a connection reset causes aardvark-dns to enter an unrecoverable infinite error loop at 100% CPU. This vulnerability is fixed in 1.17.1...

EUVD-2025-209280

Dual DHCP DNS Server 8.01 improperly accepts and caches UDP DNS responses without validating that the response originates from a legitimate configured upstream DNS server. The implementation matches responses primarily by TXID and inserts results into the cache, enabling a remote attacker to inje...

CVE-2026-35518

Pi-hole FTL (FTLDNS) from 6.0 up to before 6.6 is vulnerable to Remote Code Execution via newline injection in the DNS CNAME records configuration parameter (dns.cnameRecords). An authenticated attacker can inject arbitrary dnsmasq directives, enabling command execution on the host. The issue is ...

CVE-2026-35518 Pi-hole FTL affected by Remote Code Execution (RCE) via dns.cnameRecords Newline Injection

FTLDNS pihole-FTL provides an interactive API and also generates statistics for Pi-hole's Web interface. From 6.0 to before 6.6, the Pi-hole FTL engine contains a Remote Code Execution RCE vulnerability in the DNS CNAME records configuration parameter dns.cnameRecords. This vulnerability allows a...

CVE-2026-35517

Pi-hole FTL (FTLDNS) contains a Remote Code Execution flaw from 6.0 up to before 6.6 in the upstream DNS servers configuration (dns.upstreams). An authenticated attacker can inject arbitrary dnsmasq directives via newline characters, leading to command execution on the host. The issue is fixed in...
