---|---|---|---|---|---|
CVE-2019-16866 | 2 Canonical, Nlnetlabs | 2 Ubuntu Linux, Unbound | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
Unbound before 1.9.4 accesses uninitialized memory, which allows remote attackers to trigger a crash via a crafted NOTIFY query. The source IP address of the query must match an access-control rule. | |||||
CVE-2017-15105 | 3 Canonical, Debian, Nlnetlabs | 3 Ubuntu Linux, Debian Linux, Unbound | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
A flaw was found in the way unbound before 1.6.8 validated wildcard-synthesized NSEC records. An improperly validated wildcard NSEC record could be used to prove the non-existence (NXDOMAIN answer) of an existing wildcard record, or trick unbound into accepting a NODATA proof. | |||||
CVE-2014-8602 | 3 Canonical, Debian, Nlnetlabs | 3 Ubuntu Linux, Debian Linux, Unbound | 2024-11-21 | 4.3 MEDIUM | N/A |
iterator.c in NLnet Labs Unbound before 1.5.1 does not limit delegation chaining, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a large or infinite number of referrals. | |||||
CVE-2011-1922 | 1 Nlnetlabs | 1 Unbound | 2024-11-21 | 4.3 MEDIUM | N/A |
daemon/worker.c in Unbound 1.x before 1.4.10, when debugging functionality and the interface-automatic option are enabled, allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted DNS request that triggers improper error handling. | |||||
CVE-2010-0969 | 1 Nlnetlabs | 1 Unbound | 2024-11-21 | 5.0 MEDIUM | N/A |
Unbound before 1.4.3 does not properly align structures on 64-bit platforms, which allows remote attackers to cause a denial of service (daemon crash) via unspecified vectors. | |||||
CVE-2009-4008 | 1 Nlnetlabs | 1 Unbound | 2024-11-21 | 5.0 MEDIUM | N/A |
Unbound before 1.4.4 does not send responses for signed zones after mishandling an unspecified query, which allows remote attackers to cause a denial of service (DNSSEC outage) via a crafted query. | |||||
CVE-2009-3602 | 1 Nlnetlabs | 1 Unbound | 2024-11-21 | 7.5 HIGH | N/A |
Unbound before 1.3.4 does not properly verify signatures for NSEC3 records, which allows remote attackers to cause secure delegations to be downgraded via DNS spoofing or other DNS-related attacks in conjunction with crafted delegation responses. | |||||
CVE-2023-50387 | 8 Fedoraproject, Isc, Microsoft and 5 more | 13 Fedora, Bind, Windows Server 2008 and 10 more | 2024-06-10 | N/A | 7.5 HIGH |
Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the "KeyTrap" issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG records. |
