CVE-2022-38178 4 Debian, Fedoraproject, Isc and 1 more 4 Debian Linux, Fedora, Bind and 1 more 2025-05-28 N/A 7.5 HIGH
By spoofing the target resolver with responses that have a malformed EdDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode available memory to the point where named crashes for lack of resources.
CVE-2022-38177 4 Debian, Fedoraproject, Isc and 1 more 4 Debian Linux, Fedora, Bind and 1 more 2025-05-28 N/A 7.5 HIGH
By spoofing the target resolver with responses that have a malformed ECDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode available memory to the point where named crashes for lack of resources.
CVE-2022-2906 1 Isc 1 Bind 2025-05-28 N/A 7.5 HIGH
An attacker can leverage this flaw to gradually erode available memory to the point where named crashes for lack of resources. Upon restart the attacker would have to begin again, but nevertheless there is the potential to deny service.
CVE-2022-2881 1 Isc 1 Bind 2025-05-28 N/A 5.5 MEDIUM
The underlying bug might cause read past end of the buffer and either read memory it should not read, or crash the process.
CVE-2023-50387 8 Fedoraproject, Isc, Microsoft and 5 more 13 Fedora, Bind, Windows Server 2008 and 10 more 2025-05-12 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.

named in ISC BIND 9.9.9-P4, 9.9.9-S6, 9.10.4-P4, and 9.11.0-P1 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a response containing an inconsistency among the DNSSEC-related RRsets.
CVE-2016-9131 4 Debian, Isc, Netapp and 1 more 12 Debian Linux, Bind, Data Ontap Edge and 9 more 2025-04-20 5.0 MEDIUM 7.5 HIGH

CVE-2014-3859 1 Isc 1 Bind 2025-04-12 5.0 MEDIUM N/A
libdns in ISC BIND 9.10.0 before P2 does not properly handle EDNS options, which allows remote attackers to cause a denial of service (REQUIRE assertion failure and daemon exit) via a crafted packet, as demonstrated by an attack against named, dig, or delv.
CVE-2014-8500 1 Isc 1 Bind 2025-04-12 7.8 HIGH N/A
ISC BIND 9.0.x through 9.8.x, 9.9.0 through 9.9.6, and 9.10.0 through 9.10.1 does not limit delegation chaining, which allows remote attackers to cause a denial of service (memory consumption and named crash) via a large or infinite number of referrals.
CVE-2015-8461 1 Isc 1 Bind 2025-04-12 7.1 HIGH N/A
Race condition in resolver.c in named in ISC BIND 9.9.8 before 9.9.8-P2 and 9.10.3 before 9.10.3-P2 allows remote attackers to cause a denial of service (INSIST assertion failure and daemon exit) via unspecified vectors.
CVE-2016-1286 7 Canonical, Debian, Fedoraproject and 4 more 47 Ubuntu Linux, Debian Linux, Fedora and 44 more 2025-04-12 5.0 MEDIUM 8.6 HIGH
named in ISC BIND 9.x before 9.9.8-P4 and 9.10.x before 9.10.3-P4 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted signature record for a DNAME record, related to db.c and resolver.c.

buffer.c in named in ISC BIND 9 before 9.9.9-P3, 9.10.x before 9.10.4-P3, and 9.11.x before 9.11.0rc3 does not properly construct responses, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted query.
CVE-2016-1285 7 Canonical, Debian, Fedoraproject and 4 more 47 Ubuntu Linux, Debian Linux, Fedora and 44 more 2025-04-12 4.3 MEDIUM 6.8 MEDIUM
named in ISC BIND 9.x before 9.9.8-P4 and 9.10.x before 9.10.3-P4 does not properly handle DNAME records when parsing fetch reply messages, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a malformed packet to the rndc (aka control channel) interface, related to alist.c and sexpr.c.
CVE-2016-6170 2 Isc, Redhat 2 Bind, Enterprise Linux 2025-04-12 4.0 MEDIUM 6.5 MEDIUM
ISC BIND through 9.9.9-P1, 9.10.x through 9.10.4-P1, and 9.11.x through 9.11.0b1 allows primary DNS servers to cause a denial of service (secondary DNS server crash) via a large AXFR response, and possibly allows IXFR servers to cause a denial of service (IXFR client crash) via a large IXFR response and allows remote authenticated users to cause a denial of service (primary DNS server crash) via a large UPDATE message.
