The DHCPv6 server in ISC DHCP 4.0.x and 4.1.x before 4.1.2-P1, 4.0-ESV and 4.1-ESV before 4.1-ESV-R1, and 4.2.x before 4.2.1b1 allows remote attackers to cause a denial of service (assertion failure and daemon crash) by sending a message over IPv6 for a declined and abandoned address. | |||||
CVE-2008-1447 | 6 Canonical, Cisco, Debian and 3 more | 8 Ubuntu Linux, Ios, Debian Linux and 5 more | 2020-03-24 | 5.0 MEDIUM | 6.8 MEDIUM |
The DNS protocol, as implemented in (1) BIND 8 and 9 before 9.5.0-P1, 9.4.2-P1, and 9.3.5-P1; (2) Microsoft DNS in Windows 2000 SP4, XP SP2 and SP3, and Server 2003 SP1 and SP2; and other implementations allow remote attackers to spoof DNS traffic via a birthday attack that uses in-bailiwick referrals to conduct cache poisoning against recursive resolvers, related to insufficient randomness of DNS transaction IDs and source ports, aka "DNS Insufficient Socket Entropy Vulnerability" or "the Kaminsky bug." | |||||
CVE-2018-5732 | 1 Isc | 1 Dhcp | 2020-01-09 | 5.0 MEDIUM | 7.5 HIGH |
Failure to properly bounds-check a buffer used for processing DHCP options allows a malicious server (or an entity masquerading as a server) to cause a buffer overflow (and resulting crash) in dhclient by sending a response containing a specially constructed options section. Affects ISC DHCP versions 4.1.0 -> 4.1-ESV-R15, 4.2.0 -> 4.2.8, 4.3.0 -> 4.3.6, 4.4.0 | |||||

CVE-2016-2774 | 3 Canonical, Debian, Isc | 3 Ubuntu Linux, Debian Linux, Dhcp | 2020-01-08 | 7.1 HIGH | 5.9 MEDIUM |
ISC DHCP 4.1.x before 4.1-ESV-R13 and 4.2.x and 4.3.x before 4.3.4 does not restrict the number of concurrent TCP sessions, which allows remote attackers to cause a denial of service (INSIST assertion failure or request-processing outage) by establishing many sessions. | |||||
CVE-2012-3955 | 3 Canonical, Debian, Isc | 3 Ubuntu Linux, Debian Linux, Dhcp | 2020-01-08 | 7.1 HIGH | N/A |
ISC DHCP 4.1.x before 4.1-ESV-R7 and 4.2.x before 4.2.4-P2 allows remote attackers to cause a denial of service (daemon crash) in opportunistic circumstances by establishing an IPv6 lease in an environment where the lease expiration time is later reduced. | |||||
CVE-2011-2748 | 3 Canonical, Debian, Isc | 3 Ubuntu Linux, Debian Linux, Dhcp | 2020-01-08 | 7.8 HIGH | N/A |
The server in ISC DHCP 3.x and 4.x before 4.2.2, 3.1-ESV before 3.1-ESV-R3, and 4.1-ESV before 4.1-ESV-R3 allows remote attackers to cause a denial of service (daemon exit) via a crafted DHCP packet. | |||||
CVE-2015-8000 | 2 Isc, Oracle | 4 Bind, Linux, Solaris and 1 more | 2019-12-27 | 5.0 MEDIUM | N/A |
db.c in named in ISC BIND 9.x before 9.9.8-P2 and 9.10.x before 9.10.3-P2 allows remote attackers to cause a denial of service (REQUIRE assertion failure and daemon exit) via a malformed class attribute. | |||||

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-2019-6468 | 1 Isc | 1 Bind | 2019-12-18 | 5.0 MEDIUM | 7.5 HIGH |
In BIND Supported Preview Edition, an error in the nxdomain-redirect feature can occur in versions which support EDNS Client Subnet (ECS) features. In those versions which have ECS support, enabling nxdomain-redirect is likely to lead to BIND exiting due to assertion failure. Versions affected: BIND Supported Preview Edition version 9.10.5-S1 -> 9.11.5-S5. ONLY BIND Supported Preview Edition releases are affected. | |||||
CVE-2018-5743 | 2 F5, Isc | 17 Big-ip Access Policy Manager, Big-ip Advanced Firewall Manager, Big-ip Analytics and 14 more | 2019-12-18 | 4.3 MEDIUM | 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-2019-6467 | 1 Isc | 1 Bind | 2019-12-18 | 5.0 MEDIUM | 7.5 HIGH |
A programming error in the nxdomain-redirect feature can cause an assertion failure in query.c if the alternate namespace used by nxdomain-redirect is a descendant of a zone that is served locally. The most likely scenario where this might occur is if the server, in addition to performing NXDOMAIN redirection for recursive clients, is also serving a local copy of the root zone or using mirroring to provide the root zone, although other configurations are also possible. Versions affected: BIND 9.12.0-> 9.12.4, 9.14.0. Also affects all releases in the 9.13 development branch. | |||||
CVE-2019-6465 | 2 Isc, Redhat | 2 Bind, Enterprise Linux | 2019-12-16 | 4.3 MEDIUM | 5.3 MEDIUM |
Controls for zone transfers may not be properly applied to Dynamically Loadable Zones (DLZs) if the zones are writable Versions affected: BIND 9.9.0 -> 9.10.8-P1, 9.11.0 -> 9.11.5-P2, 9.12.0 -> 9.12.3-P2, and versions 9.9.3-S1 -> 9.11.5-S3 of BIND 9 Supported Preview Edition. Versions 9.13.0 -> 9.13.6 of the 9.13 development branch are also affected. Versions prior to BIND 9.9.0 have not been evaluated for vulnerability to CVE-2019-6465. | |||||
CVE-2019-6472 | 1 Isc | 1 Kea | 2019-12-05 | 3.3 LOW | 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-2013-5661 | 4 Isc, Nic, Nlnetlabs and 1 more | 4 Bind, Knot Resolver, Nsd and 1 more | 2019-11-08 | 2.6 LOW | 5.9 MEDIUM |
Cache Poisoning issue exists in DNS Response Rate Limiting. | |||||
CVE-2018-5742 | 2 Isc, Redhat | 2 Bind, Enterprise Linux | 2019-11-07 | 4.3 MEDIUM | 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-2019-6470 | 3 Isc, Opensuse, Redhat | 6 Bind, Dhcpd, Leap and 3 more | 2019-11-06 | 5.0 MEDIUM | 7.5 HIGH |
There had existed in one of the ISC BIND libraries a bug in a function that was used by dhcpd when operating in DHCPv6 mode. There was also a bug in dhcpd relating to the use of this function per its documentation, but the bug in the library function prevented this from causing any harm. All releases of dhcpd from ISC contain copies of this, and other, BIND libraries in combinations that have been tested prior to release and are known to not present issues like this. Some third-party packagers of ISC software have modified the dhcpd source, BIND source, or version matchup in ways that create the crash potential. Based on reports available to ISC, the crash probability is large and no analysis has been done on how, or even if, the probability can be manipulated by an attacker. Affects: Builds of dhcpd versions prior to version 4.4.1 when using BIND versions 9.11.2 or later, or BIND versions with specific bug fixes backported to them. ISC does not have access to comprehensive version lists for all repackagings of dhcpd that are vulnerable. In particular, builds from other vendors may also be affected. Operators are advised to consult their vendor documentation. | |||||
CVE-2018-5745 | 1 Isc | 1 Bind | 2019-11-05 | 3.5 LOW | 4.9 MEDIUM |
"managed-keys" is a feature which allows a BIND resolver to automatically maintain the keys used by trust anchors which operators configure for use in DNSSEC validation. Due to an error in the managed-keys feature it is possible for a BIND server which uses managed-keys to exit due to an assertion failure if, during key rollover, a trust anchor's keys are replaced with keys which use an unsupported algorithm. Versions affected: BIND 9.9.0 -> 9.10.8-P1, 9.11.0 -> 9.11.5-P1, 9.12.0 -> 9.12.3-P1, and versions 9.9.3-S1 -> 9.11.5-S3 of BIND 9 Supported Preview Edition. Versions 9.13.0 -> 9.13.6 of the 9.13 development branch are also affected. Versions prior to BIND 9.9.0 have not been evaluated for vulnerability to CVE-2018-5745. |
