unbound -- vulnerability in the processing of wildcard synthesized NSEC records

Unbound reports: We discovered a vulnerability in the processing of wildcard synthesized NSEC records. While synthesis of NSEC records is allowed by RFC4592, these synthesized owner names should not be used in the NSEC processing. This does, however, happen in Unbound 1.6.7 and earlier versions...

Weblate: DNSSEC Zone Walk using NSEC Records

Due to a design flaw in the NSEC records used by DNSSEC it is possible to discover all subdomains of a particular domain for which NSEC records are available. NSEC records are used by the weblate.org domain which means anyone can retreive all subdomains of weblate.org. These subdomains can contai...

Skyliner: DNSSEC misconfiguration

First of all I will start with some theory. DNS is a system to translate a domain name to an ip address. Normally a computer automatically trust a DNS server and connects to the IP provided by the DNS server. This is prone to security issues because a malicious wifi network, an attacker on your...

DNSSEC NSEC Records

The remote DNSSEC server uses NSEC records for negative answers to queries for its zones. NSEC records link to additional existing domains. These existing domains can be used to craft further queries that will lead to further NSEC records and thus further domains. This process can be repeated unt...

tls-nextprotoneg NSE Script

Enumerates a TLS server's supported protocols by using the next protocol negotiation extension. This works by adding the next protocol negotiation extension in the client hello packet and parsing the returned server hello's NPN extension data. For more information, see: Script Arguments...

DEBIAN-CVE-2011-4869

validator/valnsec3.c in Unbound before 1.4.13p2 does not properly perform proof processing for NSEC3-signed zones, which allows remote DNS servers to cause a denial of service daemon crash via a malformed response that lacks expected NSEC3 records, a different vulnerability than CVE-2011-4528...

dns-nsec-enum NSE Script

Enumerates DNS names using the DNSSEC NSEC-walking technique. Output is arranged by domain. Within a domain, subzones are shown with increased indentation. The NSEC response record in DNSSEC is used to give negative answers to queries, but it has the side effect of allowing enumeration of all...
