CVE-2018-5733 | 4 Canonical, Debian, Isc and 1 more | 9 Ubuntu Linux, Debian Linux, Dhcp and 6 more | 2024-09-17 | 7.5 High |
A malicious client which is allowed to send very large amounts of traffic (billions of packets) to a DHCP server can eventually overflow a 32-bit reference counter, potentially causing dhcpd to crash. Affects ISC DHCP 4.1.0 -> 4.1-ESV-R15, 4.2.0 -> 4.2.8, 4.3.0 -> 4.3.6, 4.4.0. | ||||
CVE-2017-3140 | 2 Isc, Netapp | 4 Bind, Data Ontap Edge, Element Software and 1 more | 2024-09-17 | N/A |
If named is configured to use Response Policy Zones (RPZ) an error processing some rule types can lead to a condition where BIND will endlessly loop while handling a query. Affects BIND 9.9.10, 9.10.5, 9.11.0->9.11.1, 9.9.10-S1, 9.10.5-S1. | ||||
CVE-2022-1183 | 2 Isc, Netapp | 11 Bind, H300s, H300s Firmware and 8 more | 2024-09-17 | 7.5 High |
On vulnerable configurations, the named daemon may, in some circumstances, terminate with an assertion failure. Vulnerable configurations are those that include a reference to http within the listen-on statements in their named.conf. TLS is used by both DNS over TLS (DoT) and DNS over HTTPS (DoH), but configurations using DoT alone are unaffected. Affects BIND 9.18.0 -> 9.18.2 and version 9.19.0 of the BIND 9.19 development branch. | ||||
CVE-2022-2881 | 1 Isc | 1 Bind | 2024-09-17 | 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-2019-6472 | 1 Isc | 1 Kea | 2024-09-17 | 6.5 Medium |
A packet containing a malformed DUID can cause the Kea DHCPv6 server process (kea-dhcp6) to exit due to an assertion failure. Versions affected: 1.4.0 to 1.5.0, 1.6.0-beta1, and 1.6.0-beta2. | ||||
CVE-2018-5742 | 2 Isc, Redhat | 2 Bind, Enterprise Linux | 2024-09-17 | 7.5 High |
While backporting a feature for a newer branch of BIND9, RedHat introduced a path leading to an assertion failure in buffer.c:420. Affects RedHat versions bind-9.9.4-65.el7 -> bind-9.9.4-72.el7. No ISC releases are affected. Other packages from other distributions who made the same error may also be affected. | ||||
CVE-2022-2906 | 1 Isc | 1 Bind | 2024-09-17 | 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-2020-8619 | 7 Canonical, Debian, Fedoraproject and 4 more | 7 Ubuntu Linux, Debian Linux, Fedora and 4 more | 2024-09-17 | 4.9 Medium |
In ISC BIND9 versions BIND 9.11.14 -> 9.11.19, BIND 9.14.9 -> 9.14.12, BIND 9.16.0 -> 9.16.3, BIND Supported Preview Edition 9.11.14-S1 -> 9.11.19-S1: Unless a nameserver is providing authoritative service for one or more zones and at least one zone contains an empty non-terminal entry containing an asterisk ("*") character, this defect cannot be encountered. A would-be attacker who is allowed to change zone content could theoretically introduce such a record in order to exploit this condition to cause denial of service, though we consider the use of this vector unlikely because any such attack would require a significant privilege level and be easily traceable. | ||||
CVE-2020-8623 | 8 Canonical, Debian, Fedoraproject and 5 more | 9 Ubuntu Linux, Debian Linux, Fedora and 6 more | 2024-09-17 | 7.5 High |
In BIND 9.10.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.10.5-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker that can reach a vulnerable system with a specially crafted query packet can trigger a crash. To be vulnerable, the system must: * be running BIND that was built with "--enable-native-pkcs11" * be signing one or more zones with an RSA key * be able to receive queries from a possible attacker | ||||
CVE-2021-25218 | 2 Fedoraproject, Isc | 2 Fedora, Bind | 2024-09-17 | 7.5 High |
In BIND 9.16.19, 9.17.16. Also, version 9.16.19-S1 of BIND Supported Preview Edition When a vulnerable version of named receives a query under the circumstances described above, the named process will terminate due to a failed assertion check. The vulnerability affects only BIND 9 releases 9.16.19, 9.17.16, and release 9.16.19-S1 of the BIND Supported Preview Edition. | ||||
CVE-2022-2795 | 4 Debian, Fedoraproject, Isc and 1 more | 5 Debian Linux, Fedora, Bind and 2 more | 2024-09-17 | 5.3 Medium |
By flooding the target resolver with queries exploiting this flaw an attacker can significantly impair the resolver's performance, effectively denying legitimate clients access to the DNS resolution service. | ||||
CVE-2022-38178 | 5 Debian, Fedoraproject, Isc and 2 more | 8 Debian Linux, Fedora, Bind and 5 more | 2024-09-17 | 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-2018-5734 | 2 Isc, Netapp | 3 Bind, Data Ontap Edge, Solidfire Element Os Management Node | 2024-09-17 | N/A |
While handling a particular type of malformed packet BIND erroneously selects a SERVFAIL rcode instead of a FORMERR rcode. If the receiving view has the SERVFAIL cache feature enabled, this can trigger an assertion failure in badcache.c when the request doesn't contain all of the expected information. Affects BIND 9.10.5-S1 to 9.10.5-S4, 9.10.6-S1, 9.10.6-S2. | ||||
CVE-2018-5741 | 2 Isc, Redhat | 2 Bind, Enterprise Linux | 2024-09-17 | N/A |
To provide fine-grained controls over the ability to use Dynamic DNS (DDNS) to update records in a zone, BIND 9 provides a feature called update-policy. Various rules can be configured to limit the types of updates that can be performed by a client, depending on the key used when sending the update request. Unfortunately, some rule types were not initially documented, and when documentation for them was added to the Administrator Reference Manual (ARM) in change #3112, the language that was added to the ARM at that time incorrectly described the behavior of two rule types, krb5-subdomain and ms-subdomain. This incorrect documentation could mislead operators into believing that policies they had configured were more restrictive than they actually were. This affects BIND versions prior to BIND 9.11.5 and BIND 9.12.3. | ||||
CVE-2018-5743 | 3 F5, Isc, Redhat | 19 Big-ip Access Policy Manager, Big-ip Advanced Firewall Manager, Big-ip Analytics and 16 more | 2024-09-17 | 7.5 High |
By design, BIND is intended to limit the number of TCP clients that can be connected at any given time. The number of allowed connections is a tunable parameter which, if unset, defaults to a conservative value for most servers. Unfortunately, the code which was intended to limit the number of simultaneous connections contained an error which could be exploited to grow the number of simultaneous connections beyond this limit. Versions affected: BIND 9.9.0 -> 9.10.8-P1, 9.11.0 -> 9.11.6, 9.12.0 -> 9.12.4, 9.14.0. BIND 9 Supported Preview Edition versions 9.9.3-S1 -> 9.11.5-S3, and 9.11.5-S5. Versions 9.13.0 -> 9.13.7 of the 9.13 development branch are also affected. Versions prior to BIND 9.9.0 have not been evaluated for vulnerability to CVE-2018-5743. | ||||
CVE-2022-0635 | 2 Isc, Netapp | 17 Bind, H300e, H300e Firmware and 14 more | 2024-09-17 | 7.5 High |
Versions affected: BIND 9.18.0 When a vulnerable version of named receives a series of specific queries, the named process will eventually terminate due to a failed assertion check. | ||||
CVE-2018-5739 | 1 Isc | 1 Kea | 2024-09-17 | N/A |
An extension to hooks capabilities which debuted in Kea 1.4.0 introduced a memory leak for operators who are using certain hooks library facilities. In order to support multiple requests simultaneously, Kea 1.4 added a callout handle store but unfortunately the initial implementation of this store does not properly free memory in every case. Hooks which make use of query4 or query6 parameters in their callouts can leak memory, resulting in the eventual exhaustion of available memory and subsequent failure of the server process. Affects Kea DHCP 1.4.0. | ||||
CVE-2022-3080 | 3 Fedoraproject, Isc, Redhat | 3 Fedora, Bind, Enterprise Linux | 2024-09-17 | 7.5 High |
By sending specific queries to the resolver, an attacker can cause named to crash. | ||||
CVE-2019-6471 | 3 F5, Isc, Redhat | 18 Big-ip Access Policy Manager, Big-ip Advanced Firewall Manager, Big-ip Analytics and 15 more | 2024-09-17 | 5.9 Medium |
A race condition which may occur when discarding malformed packets can result in BIND exiting due to a REQUIRE assertion failure in dispatch.c. Versions affected: BIND 9.11.0 -> 9.11.7, 9.12.0 -> 9.12.4-P1, 9.14.0 -> 9.14.2. Also all releases of the BIND 9.13 development branch and version 9.15.0 of the BIND 9.15 development branch and BIND Supported Preview Edition versions 9.11.3-S1 -> 9.11.7-S1. | ||||
CVE-2020-8620 | 4 Canonical, Isc, Netapp and 1 more | 4 Ubuntu Linux, Bind, Steelstore Cloud Integrated Storage and 1 more | 2024-09-17 | 7.5 High |
In BIND 9.15.6 -> 9.16.5, 9.17.0 -> 9.17.3, An attacker who can establish a TCP connection with the server and send data on that connection can exploit this to trigger the assertion failure, causing the server to exit. |
