CVE-2010-0290 1 Isc 1 Bind 2023-11-07 4.0 MEDIUM N/A
Unspecified vulnerability in ISC BIND 9.0.x through 9.3.x, 9.4 before 9.4.3-P5, 9.5 before 9.5.2-P2, 9.6 before 9.6.1-P3, and 9.7.0 beta, with DNSSEC validation enabled and checking disabled (CD), allows remote attackers to conduct DNS cache poisoning attacks by receiving a recursive client query and sending a response that contains (1) CNAME or (2) DNAME records, which do not have the intended validation before caching, aka Bug 20737. NOTE: this vulnerability exists because of an incomplete fix for CVE-2009-4022.
CVE-2006-0527 1 Isc 1 Bind 2023-11-07 7.5 HIGH N/A
BIND 4 (BIND4) and BIND 8 (BIND8), if used as a target forwarder, allows remote attackers to gain privileged access via a "Kashpureff-style DNS cache corruption" attack.
CVE-2023-2828 4 Debian, Fedoraproject, Isc and 1 more 14 Debian Linux, Fedora, Bind and 11 more 2023-07-21 N/A 7.5 HIGH
Every `named` instance configured to run as a recursive resolver maintains a cache database holding the responses to the queries it has recently sent to authoritative servers. The size limit for that cache database can be configured using the `max-cache-size` statement in the configuration file; it defaults to 90% of the total amount of memory available on the host. When the size of the cache reaches 7/8 of the configured limit, a cache-cleaning algorithm starts to remove expired and/or least-recently used RRsets from the cache, to keep memory use below the configured limit. It has been discovered that the effectiveness of the cache-cleaning algorithm used in `named` can be severely diminished by querying the resolver for specific RRsets in a certain order, effectively allowing the configured `max-cache-size` limit to be significantly exceeded. This issue affects BIND 9 versions 9.11.0 through 9.16.41, 9.18.0 through 9.18.15, 9.19.0 through 9.19.13, 9.11.3-S1 through 9.16.41-S1, and 9.18.11-S1 through 9.18.15-S1.
CVE-2023-2829 2 Isc, Netapp 12 Bind, Active Iq Unified Manager, H300s and 9 more 2023-07-03 N/A 7.5 HIGH
A `named` instance configured to run as a DNSSEC-validating recursive resolver with the Aggressive Use of DNSSEC-Validated Cache (RFC 8198) option (`synth-from-dnssec`) enabled can be remotely terminated using a zone with a malformed NSEC record. This issue affects BIND 9 versions 9.16.8-S1 through 9.16.41-S1 and 9.18.11-S1 through 9.18.15-S1.
CVE-2023-2911 4 Debian, Fedoraproject, Isc and 1 more 14 Debian Linux, Fedora, Bind and 11 more 2023-07-03 N/A 7.5 HIGH
If the `recursive-clients` quota is reached on a BIND 9 resolver configured with both `stale-answer-enable yes;` and `stale-answer-client-timeout 0;`, a sequence of serve-stale-related lookups could cause `named` to loop and terminate unexpectedly due to a stack overflow. This issue affects BIND 9 versions 9.16.33 through 9.16.41, 9.18.7 through 9.18.15, 9.16.33-S1 through 9.16.41-S1, and 9.18.11-S1 through 9.18.15-S1.
CVE-2017-3145 5 Debian, Isc, Juniper and 2 more 38 Debian Linux, Bind, Junos and 35 more 2023-06-21 5.0 MEDIUM 7.5 HIGH
BIND was improperly sequencing cleanup operations on upstream recursion fetch contexts, leading in some cases to a use-after-free error that can trigger an assertion failure and crash in named. Affects BIND 9.0.0 to 9.8.x, 9.9.0 to 9.9.11, 9.10.0 to 9.10.6, 9.11.0 to 9.11.2, 9.9.3-S1 to 9.9.11-S1, 9.10.5-S1 to 9.10.6-S1, 9.12.0a1 to 9.12.0rc1.
CVE-2007-0493 1 Isc 1 Bind 2023-02-13 7.8 HIGH N/A
Use-after-free vulnerability in ISC BIND 9.3.0 up to 9.3.3, 9.4.0a1 up to 9.4.0a6, 9.4.0b1 up to 9.4.0b4, 9.4.0rc1, and 9.5.0a1 (Bind Forum only) allows remote attackers to cause a denial of service (named daemon crash) via unspecified vectors that cause named to "dereference a freed fetch context."
CVE-2012-4244 1 Isc 1 Bind 2022-12-09 7.8 HIGH N/A
ISC BIND 9.x before 9.7.6-P3, 9.8.x before 9.8.3-P3, 9.9.x before 9.9.1-P3, and 9.4-ESV and 9.6-ESV before 9.6-ESV-R7-P3 allows remote attackers to cause a denial of service (assertion failure and named daemon exit) via a query for a long resource record.
CVE-2022-2906 1 Isc 1 Bind 2022-12-03 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 2022-11-16 N/A 8.2 HIGH
The underlying bug might cause read past end of the buffer and either read memory it should not read, or crash the process.
CVE-2022-1183 2 Isc, Netapp 11 Bind, H300s, H300s Firmware and 8 more 2022-10-07 4.3 MEDIUM 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-2020-8618 4 Canonical, Isc, Netapp and 1 more 4 Ubuntu Linux, Bind, Steelstore Cloud Integrated Storage and 1 more 2022-10-07 4.0 MEDIUM 4.9 MEDIUM
An attacker who is permitted to send zone data to a server via zone transfer can exploit this to intentionally trigger the assertion failure with a specially constructed zone, denying service to clients.
CVE-1999-0184 1 Isc 1 Bind 2022-08-17 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-1999-0024 6 Bsdi, Ibm, Isc and 3 more 12 Bsd Os, Aix, Bind and 9 more 2022-08-17 5.0 MEDIUM N/A
DNS cache poisoning via BIND, by predictable query IDs.
CVE-2020-8620 4 Canonical, Isc, Netapp and 1 more 4 Ubuntu Linux, Bind, Steelstore Cloud Integrated Storage and 1 more 2022-06-02 5.0 MEDIUM 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.
CVE-2021-25216 4 Debian, Isc, Netapp and 1 more 23 Debian Linux, Bind, Active Iq Unified Manager and 20 more 2022-05-03 6.8 MEDIUM 9.8 CRITICAL
In BIND 9.5.0 -> 9.11.29, 9.12.0 -> 9.16.13, and versions BIND 9.11.3-S1 -> 9.11.29-S1 and 9.16.8-S1 -> 9.16.13-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.1 of the BIND 9.17 development branch, BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed, but a server can be rendered vulnerable by explicitly setting values for the tkey-gssapi-keytab or tkey-gssapi-credential configuration options. Although the default configuration is not vulnerable, GSS-TSIG is frequently used in networks where BIND is integrated with Samba, as well as in mixed-server environments that combine BIND servers with Active Directory domain controllers. For servers that meet these conditions, the ISC SPNEGO implementation is vulnerable to various attacks, depending on the CPU architecture for which BIND was built: For named binaries compiled for 64-bit platforms, this flaw can be used to trigger a buffer over-read, leading to a server crash. For named binaries compiled for 32-bit platforms, this flaw can be used to trigger a server crash due to a buffer overflow and possibly also to achieve remote code execution. We have determined that standard SPNEGO implementations are available in the MIT and Heimdal Kerberos libraries, which support a broad range of operating systems, rendering the ISC implementation unnecessary and obsolete. Therefore, to reduce the attack surface for BIND users, we will be removing the ISC SPNEGO implementation in the April releases of BIND 9.11 and 9.16 (it had already been dropped from BIND 9.17). We would not normally remove something from a stable ESV (Extended Support Version) of BIND, but since system libraries can replace the ISC SPNEGO implementation, we have made an exception in this case for reasons of stability and security.
CVE-2020-8621 5 Canonical, Isc, Netapp and 2 more 5 Ubuntu Linux, Bind, Steelstore Cloud Integrated Storage and 2 more 2022-04-28 4.3 MEDIUM 7.5 HIGH
In BIND 9.14.0 -> 9.16.5, 9.17.0 -> 9.17.3, If a server is configured with both QNAME minimization and 'forward first' then an attacker who can send queries to it may be able to trigger the condition that will cause the server to crash. Servers that 'forward only' are not affected.
CVE-2018-5740 7 Canonical, Debian, Hp and 4 more 11 Ubuntu Linux, Debian Linux, Hp-ux and 8 more 2022-04-12 5.0 MEDIUM 7.5 HIGH
"deny-answer-aliases" is a little-used feature intended to help recursive server operators protect end users against DNS rebinding attacks, a potential method of circumventing the security model used by client browsers. However, a defect in this feature makes it easy, when the feature is in use, to experience an assertion failure in name.c. Affects BIND 9.7.0->9.8.8, 9.9.0->9.9.13, 9.10.0->9.10.8, 9.11.0->9.11.4, 9.12.0->9.12.2, 9.13.0->9.13.2.
CVE-2000-0888 2 Debian, Isc 2 Debian Linux, Bind 2020-12-09 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 sending an SRV record to the server, aka the "srv bug."
CVE-2018-5741 1 Isc 1 Bind 2020-10-20 4.0 MEDIUM 6.5 MEDIUM
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.
