CVE-2026-32936

CVE-2026-32936 – CoreDNS DoH GET path size validation issue . In CoreDNS (prior to 1.14.3), the DNS-over-HTTPS (DoH) GET path accepts oversized dns= query parameters and performs parsing, base64 decoding, and DNS message unpacking before rejection. Unlike the POST path, there is no equivalent siz...

CVE-2026-32934 CoreDNS DNS-over-QUIC unbounded goroutine growth leads to denial of service

CoreDNS is a DNS server that chains plugins. In versions prior to 1.14.3, the DNS-over-QUIC DoQ server can be driven into unbounded goroutine and memory growth by a remote client that opens many QUIC streams and sends only 1 byte per stream. When the worker pool is full, CoreDNS still spawns a...

CVE-2026-33190 CoreDNS TSIG authentication bypass on encrypted DNS transports

CoreDNS is a DNS server that chains plugins. In versions prior to 1.14.3, the tsig plugin can be bypassed on non-plain-DNS transports DoT, DoH, DoH3, DoQ, and gRPC because it trusts the transport writer's TsigStatus instead of performing verification itself. The DoH and DoH3 writer's TsigStatus...

CVE-2026-40684

A flaw was found in Exim, specifically on systems utilizing musl libc. A remote attacker can exploit this vulnerability by providing malformed DNS data within PTR records. This can lead to the mail transfer agent MTA connection instance crashing, resulting in a Denial of Service DoS for affected...

CVE-2026-6238

A flaw was found in glibc GNU C Library. The deprecated functions nsprintrrf, nsprintrr, and fpnquery do not properly validate the length of RDATA Resource Record Data in a DNS Domain Name System response when processing specific record types like LOC, CERT, TKEY, or TSIG. A remote attacker could...

CoreDNS 资源管理错误漏洞

CoreDNS is a DNS server within the CoreDNS community. Versions of CoreDNS prior to 1.14.3 contained a resource management vulnerability. This vulnerability stemmed from the lack of size validation for overly large dns query parameters in the DNS-over-HTTPS GET path, which could allow remote...

PT-2026-38372

Name of the Vulnerable Software and Affected Versions Netty versions prior to 4.1.133.Final Netty versions prior to 4.2.13.Final Description Netty's DNS codec fails to enforce RFC 1035 domain name constraints during encoding and decoding, creating a bidirectional attack surface. In the encoder, t...

Async http client/server framework asyncio. Security Fixes: Insufficient restrictions in header/trailer handling could cause uncapped memory usage.CVE-2026-22815 An unbounded DNS cache could result in excessive memory usage possibly resulting in a DoS situation.CVE-2026-34513 An attacker who...

gnutls: GnuTLS: Policy bypass due to case-sensitive nameConstraints comparison

A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of nameConstraints labels, specifically for dNSName DNS or rfc822Name email constraints within excludedSubtrees or permittedSubtrees. A remote attacker can exploit this by crafting a leaf...

glibc: glibc: Application crash or uninitialized memory read via crafted DNS response

A flaw was found in glibc GNU C Library. The deprecated functions nsprintrrf, nsprintrr, and fpnquery do not properly validate the length of RDATA Resource Record Data in a DNS Domain Name System response when processing specific record types like LOC, CERT, TKEY, or TSIG. A remote attacker could...

Wireshark 2.0.x < 2.0.13 Multiple Vulnerabilities (macOS)

The version of Wireshark installed on the remote macOS / Mac OS X host is prior to 2.0.13. It is, therefore, affected by multiple vulnerabilities as referenced in the wireshark-2.0.13 advisory. - In Wireshark 2.2.0 to 2.2.6 and 2.0.0 to 2.0.12, the RGMP dissector could crash. This was addressed i...

SUSE CVE-2026-6238

The deprecated functions nsprintrrf, nsprintrr and fpnquery in the GNU C Library version 2.0.1 to version 2.43 fail to validate the RDATA content against the RDATA length in a DNS response when processing A6, CERT, LOC, TKEY or TSIG records, which may allow an attacker to craft a DNS response,...

EUVD-2026-26442
