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...

CVE-2026-12039
Docker Sandboxes sbx enforces an HTTP/S-only egress allowlist but does not apply it to DNS resolution: the per-network embedded DNS server forwards any queried name to the host resolver whenever the network is internet-connected, without consulting the policy. A workload inside a sandbox, which t...
CVE-2026-12039
Docker Sandboxes (sbx) expose a DNS resolution bypass: the per-network embedded DNS server forwards queries to the host resolver when the network is internet-connected, ignoring the HTTP/S egress allowlist. This enables a workload treated as untrusted to encode data in DNS labels for an attacker-...

A workload inside a sandbox, which t...
io.netty/netty-resolver-dns: Netty has Insufficient Bailiwick Validation for NS Records
A flaw was found in Netty's DnsResolveContext. An attacker controlling an authoritative name server for a subdomain can exploit this vulnerability by providing crafted NS records that are insufficiently validated. This allows the attacker to poison the DNS cache for parent domains, bypassing...
netty-resolver-dns: Netty: Information disclosure and data manipulation due to improper CNAME record validation
A flaw was found in Netty's DnsResolveContext. This vulnerability allows a remote attacker to achieve information disclosure or data manipulation by crafting malicious DNS responses. The flaw occurs because the DnsResolveContext fails to validate the origin bailiwick of CNAME records in DNS...

netty-resolver-dns: Netty DNS resolver: DNS Cache Poisoning via predictable transaction IDs
A flaw was found in Netty's DNS resolver component. This vulnerability arises from the use of a predictable pseudo-random number generator PRNG for DNS transaction IDs and a static User Datagram Protocol UDP source port. This combination significantly reduces the randomness of DNS queries, making...

TypeBot is a chatbot builder tool. In versions prior to 3.17.2, SSRF validation is implemented by resolving a hostname once and checking whether the resolved IP belongs to a forbidden range allowing for DNS rebinding bypass. The root cause is a time-of-check to time-of-use gap in the SSRF guard...
gnutls: gnutls: Certificate validation bypass due to improper handling of URI and SRV SANs
A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted certificate that contains Uniform Resource Identifier URI or Service SRV Subject Alternative Names SANs. This could cause the certificate validation process to incorrectly fall back to...
SUSE CVE-2026-45674
Netty is a network application framework for development of protocol servers and clients. Prior to versions 4.1.135.Final and 4.2.15.Final, Netty's DnsResolveContext fails to validate the origin bailiwick of CNAME records in DNS responses. Versions 4.1.135.Final and 4.2.15.Final patch the issue...
