CVE-1999-0837 2 Isc, Sun 3 Bind, Solaris, Sunos 2025-04-03 10.0 HIGH N/A
Denial of service in BIND by improperly closing TCP sessions via so_linger.
CVE-2004-0045 1 Isc 1 Inn 2025-04-03 7.5 HIGH N/A
Buffer overflow in the ARTpost function in art.c in the control message handling code for INN 2.4.0 may allow remote attackers to execute arbitrary code.
CVE-2006-0987 1 Isc 1 Bind 2025-04-03 5.0 MEDIUM N/A
The default configuration of ISC BIND before 9.4.1-P1, when configured as a caching name server, allows recursive queries and provides additional delegation information to arbitrary IP addresses, which allows remote attackers to cause a denial of service (traffic amplification) via DNS queries with spoofed source IP addresses.
CVE-2000-0887 1 Isc 1 Bind 2025-04-03 5.0 MEDIUM N/A
named in BIND 8.2 through 8.2.2-P6 allows remote attackers to cause a denial of service by making a compressed zone transfer (ZXFR) request and performing a name service query on an authoritative record that is not cached, aka the "zxfr bug."
CVE-2002-1221 3 Freebsd, Isc, Openbsd 3 Freebsd, Bind, Openbsd 2025-04-03 5.0 MEDIUM N/A
BIND 8.x through 8.3.3 allows remote attackers to cause a denial of service (crash) via SIG RR elements with invalid expiry times, which are removed from the internal BIND database and later cause a null dereference.
CVE-2002-0400 1 Isc 1 Bind 2025-04-03 5.0 MEDIUM N/A
ISC BIND 9 before 9.2.1 allows remote attackers to cause a denial of service (shutdown) via a malformed DNS packet that triggers an error condition that is not properly handled when the rdataset parameter to the dns_message_findtype() function in message.c is not NULL, aka DoS_findtype.
CVE-2002-1220 3 Freebsd, Isc, Openbsd 3 Freebsd, Bind, Openbsd 2025-04-03 5.0 MEDIUM N/A
BIND 8.3.x through 8.3.3 allows remote attackers to cause a denial of service (termination due to assertion failure) via a request for a subdomain that does not exist, with an OPT resource record with a large UDP payload size.
CVE-2002-0684 2 Gnu, Isc 2 Glibc, Bind 2025-04-03 7.5 HIGH N/A
Buffer overflow in DNS resolver functions that perform lookup of network names and addresses, as used in BIND 4.9.8 and ported to glibc 2.2.5 and earlier, allows remote malicious DNS servers to execute arbitrary code through a subroutine used by functions such as getnetbyname and getnetbyaddr.
CVE-2001-0011 1 Isc 1 Bind 2025-04-03 10.0 HIGH N/A
Buffer overflow in nslookupComplain function in BIND 4 allows remote attackers to gain root privileges.
CVE-1999-0184 1 Isc 1 Bind 2025-04-03 6.4 MEDIUM N/A
When compiled with the -DALLOW_UPDATES option, bind allows dynamic updates to the DNS server, allowing for malicious modification of DNS records.
CVE-2003-0914 9 Compaq, Freebsd, Hp and 6 more 10 Tru64, Freebsd, Hp-ux and 7 more 2025-04-03 4.3 MEDIUM N/A
ISC BIND 8.3.x before 8.3.7, and 8.4.x before 8.4.3, allows remote attackers to poison the cache via a malicious name server that returns negative responses with a large TTL (time-to-live) value.
CVE-2001-1442 1 Isc 1 Inn 2025-04-03 4.6 MEDIUM N/A
Buffer overflow in innfeed for ISC InterNetNews (INN) before 2.3.0 allows local users in the "news" group to gain privileges via a long -c command line argument.
CVE-2002-2213 2 Infoblox, Isc 2 Dns One, Bind 2025-04-03 5.0 MEDIUM N/A
The DNS resolver in unspecified versions of Infoblox DNS One, when resolving recursive DNS queries for arbitrary hosts, allows remote attackers to conduct DNS cache poisoning via a birthday attack that uses a large number of open queries for the same resource record (RR) combined with spoofed responses, which increases the possibility of successfully spoofing a response in a way that is more efficient than brute force methods.
CVE-2022-3736 1 Isc 1 Bind 2025-04-01 N/A 7.5 HIGH
BIND 9 resolver can crash when stale cache and stale answers are enabled, option `stale-answer-client-timeout` is set to a positive integer, and the resolver receives an RRSIG query. This issue affects BIND 9 versions 9.16.12 through 9.16.36, 9.18.0 through 9.18.10, 9.19.0 through 9.19.8, and 9.16.12-S1 through 9.16.36-S1.
CVE-2022-3488 1 Isc 1 Bind 2025-04-01 N/A 7.5 HIGH
Processing of repeated responses to the same query, where both responses contain ECS pseudo-options, but where the first is broken in some way, can cause BIND to exit with an assertion failure. 'Broken' in this context is anything that would cause the resolver to reject the query response, such as a mismatch between query and answer name. This issue affects BIND 9 versions 9.11.4-S1 through 9.11.37-S1 and 9.16.8-S1 through 9.16.36-S1.
CVE-2022-3094 1 Isc 1 Bind 2025-04-01 N/A 7.5 HIGH
Sending a flood of dynamic DNS updates may cause `named` to allocate large amounts of memory. This, in turn, may cause `named` to exit due to a lack of free memory. We are not aware of any cases where this has been exploited. Memory is allocated prior to the checking of access permissions (ACLs) and is retained during the processing of a dynamic update from a client whose access credentials are accepted. Memory allocated to clients that are not permitted to send updates is released immediately upon rejection. The scope of this vulnerability is limited therefore to trusted clients who are permitted to make dynamic zone changes. If a dynamic update is REFUSED, memory will be released again very quickly. Therefore it is only likely to be possible to degrade or stop `named` by sending a flood of unaccepted dynamic updates comparable in magnitude to a query flood intended to achieve the same detrimental outcome. BIND 9.11 and earlier branches are also affected, but through exhaustion of internal resources rather than memory constraints. This may reduce performance but should not be a significant problem for most servers. Therefore we don't intend to address this for BIND versions prior to BIND 9.16. This issue affects BIND 9 versions 9.16.0 through 9.16.36, 9.18.0 through 9.18.10, 9.19.0 through 9.19.8, and 9.16.8-S1 through 9.16.36-S1.
CVE-2022-3924 1 Isc 1 Bind 2025-03-31 N/A 7.5 HIGH
This issue can affect BIND 9 resolvers with `stale-answer-enable yes;` that also make use of the option `stale-answer-client-timeout`, configured with a value greater than zero. If the resolver receives many queries that require recursion, there will be a corresponding increase in the number of clients that are waiting for recursion to complete. If there are sufficient clients already waiting when a new client query is received so that it is necessary to SERVFAIL the longest waiting client (see BIND 9 ARM `recursive-clients` limit and soft quota), then it is possible for a race to occur between providing a stale answer to this older client and sending an early timeout SERVFAIL, which may cause an assertion failure. This issue affects BIND 9 versions 9.16.12 through 9.16.36, 9.18.0 through 9.18.10, 9.19.0 through 9.19.8, and 9.16.12-S1 through 9.16.36-S1.
CVE-2023-5679 3 Fedoraproject, Isc, Netapp 3 Fedora, Bind, Active Iq Unified Manager 2025-03-29 N/A 7.5 HIGH
A bad interaction between DNS64 and serve-stale may cause `named` to crash with an assertion failure during recursive resolution, when both of these features are enabled. This issue affects BIND 9 versions 9.16.12 through 9.16.45, 9.18.0 through 9.18.21, 9.19.0 through 9.19.19, 9.16.12-S1 through 9.16.45-S1, and 9.18.11-S1 through 9.18.21-S1.
CVE-2024-28872 1 Isc 1 Stork 2025-03-26 N/A 8.9 HIGH
The TLS certificate validation code is flawed. An attacker can obtain a TLS certificate from the Stork server and use it to connect to the Stork agent. Once this connection is established with the valid certificate, the attacker can send malicious commands to a monitored service (Kea or BIND 9), possibly resulting in confidential data loss and/or denial of service. It should be noted that this vulnerability is not related to BIND 9 or Kea directly, and only customers using the Stork management tool are potentially affected. This issue affects Stork versions 0.15.0 through 1.15.0.
CVE-2023-4408 3 Fedoraproject, Isc, Netapp 3 Fedora, Bind, Ontap 2025-03-14 N/A 7.5 HIGH
The DNS message parsing code in `named` includes a section whose computational complexity is overly high. It does not cause problems for typical DNS traffic, but crafted queries and responses may cause excessive CPU load on the affected `named` instance by exploiting this flaw. This issue affects both authoritative servers and recursive resolvers. This issue affects BIND 9 versions 9.0.0 through 9.16.45, 9.18.0 through 9.18.21, 9.19.0 through 9.19.19, 9.9.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.45-S1, and 9.18.11-S1 through 9.18.21-S1.
