CVE-2026-39155

Knot DNS before 3.4.10 and 3.5.x before 3.5.4 contain a vulnerability in mod-onlinesign where the next NSEC owner name can be computed incorrectly, creating an overly broad authenticated denial interval. This enables downstream validating resolvers using aggressive negative caching to synthesize ...

USN-8591-1 python-aiohttp vulnerabilities

Sean Gilligan discovered that AIOHTTP did not properly limit memory usage when processing HTTP headers and trailers. An attacker could possibly use this issue to consume excessive system resources, resulting in a denial of service. CVE-2026-22815 It was discovered that AIOHTTP did not properly...

CVE-2026-40691

A flaw was found in Unbound, a domain name system DNS resolver. When Unbound is configured with DNSCrypt support, a remote attacker could send a specially crafted DNSCrypt query over TCP. This malicious query could cause a memory error, leading to a server crash and a Denial of Service DoS. This...

CVE-2026-11721

It is possible for an attacker's zone to respond to a query with an RRSIG that has a smaller number of labels than the zone in which the RRSIG is contained. This causes named to produce a wildcard name for a zone that is shorter than the attacker's zone, which can result in cache poisoning. For...

CVE-2026-12617

The issue is unexpected program termination based on ordering and/or specific content in responses to queries for CNAME or DNAME, and A records. Specifically, if a client queries for a DNAME and A record below the DNAME to the resolver, and the authoritative server responds positively to the A...

CVE-2026-11605

The issue is a resource exhaustion vulnerability associated with DNSSEC validation. BIND always validates all RRSIG records in an answer, even if they are not strictly needed. A query to an authoritative server/zone which returns many valid but superfluous RRSIG records causes the validator to...

CVE-2026-13321

The BIND resolver accepts validly-signed NSEC records where the "Next Domain Name" field points outside the signer's zone. Mitigation Disclaimer: The following mitigation notes are provided as a courtesy, pending the application of an official patch. This content was generated utilizing AI tools ...

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,...

ALPINE-CVE-2026-13204

If a provably insecure domain is covered by both an NSEC and NSEC3 record at the parent, and there exist an RRSIG for only one of these types, then BIND may exit unexpectedly with an assertion while validating this proof. This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through...
