CVE-2011-4539 3 Canonical, Debian, Isc 3 Ubuntu Linux, Debian Linux, Dhcp 2025-04-11 5.0 MEDIUM N/A
dhcpd in ISC DHCP 4.x before 4.2.3-P1 and 4.1-ESV before 4.1-ESV-R4 does not properly handle regular expressions in dhcpd.conf, which allows remote attackers to cause a denial of service (daemon crash) via a crafted request packet.
CVE-2012-5688 2 Canonical, Isc 2 Ubuntu Linux, Bind 2025-04-11 7.8 HIGH N/A
ISC BIND 9.8.x before 9.8.4-P1 and 9.9.x before 9.9.2-P1, when DNS64 is enabled, allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted query.
CVE-2010-0290 1 Isc 1 Bind 2025-04-11 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-2011-0413 1 Isc 1 Dhcp 2025-04-11 7.8 HIGH N/A
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-2011-2748 3 Canonical, Debian, Isc 3 Ubuntu Linux, Debian Linux, Dhcp 2025-04-11 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-2012-3817 1 Isc 1 Bind 2025-04-11 7.8 HIGH N/A
ISC BIND 9.4.x, 9.5.x, 9.6.x, and 9.7.x before 9.7.6-P2; 9.8.x before 9.8.3-P2; 9.9.x before 9.9.1-P2; and 9.6-ESV before 9.6-ESV-R7-P2, when DNSSEC validation is enabled, does not properly initialize the failing-query cache, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) by sending many queries.
CVE-2012-1033 1 Isc 1 Bind 2025-04-11 5.0 MEDIUM N/A
The resolver in ISC BIND 9 through 9.8.1-P1 overwrites cached server names and TTL values in NS records during the processing of a response to an A record query, which allows remote attackers to trigger continued resolvability of revoked domain names via a "ghost domain names" attack.
CVE-2011-1910 1 Isc 1 Bind 2025-04-11 5.0 MEDIUM N/A
Off-by-one error in named in ISC BIND 9.x before 9.7.3-P1, 9.8.x before 9.8.0-P2, 9.4-ESV before 9.4-ESV-R4-P1, and 9.6-ESV before 9.6-ESV-R4-P1 allows remote DNS servers to cause a denial of service (assertion failure and daemon exit) via a negative response containing large RRSIG RRsets.
CVE-2011-4868 1 Isc 1 Dhcp 2025-04-11 6.1 MEDIUM N/A
The logging functionality in dhcpd in ISC DHCP before 4.2.3-P2, when using Dynamic DNS (DDNS) and issuing IPv6 addresses, does not properly handle the DHCPv6 lease structure, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via crafted packets related to a lease-status update.
CVE-2013-3919 1 Isc 1 Bind 2025-04-11 7.8 HIGH N/A
resolver.c in ISC BIND 9.8.5 before 9.8.5-P1, 9.9.3 before 9.9.3-P1, and 9.6-ESV-R9 before 9.6-ESV-R9-P1, when a recursive resolver is configured, allows remote attackers to cause a denial of service (assertion failure and named daemon exit) via a query for a record in a malformed zone.
CVE-2012-3955 3 Canonical, Debian, Isc 3 Ubuntu Linux, Debian Linux, Dhcp 2025-04-11 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-2012-1667 1 Isc 1 Bind 2025-04-11 8.5 HIGH N/A
ISC BIND 9.x before 9.7.6-P1, 9.8.x before 9.8.3-P1, 9.9.x before 9.9.1-P1, and 9.4-ESV and 9.6-ESV before 9.6-ESV-R7-P1 does not properly handle resource records with a zero-length RDATA section, which allows remote DNS servers to cause a denial of service (daemon crash or data corruption) or obtain sensitive information from process memory via a crafted record.
CVE-2014-0591 1 Isc 1 Bind 2025-04-11 2.6 LOW N/A
The query_findclosestnsec3 function in query.c in named in ISC BIND 9.6, 9.7, and 9.8 before 9.8.6-P2 and 9.9 before 9.9.4-P2, and 9.6-ESV before 9.6-ESV-R10-P2, allows remote attackers to cause a denial of service (INSIST assertion failure and daemon exit) via a crafted DNS query to an authoritative nameserver that uses the NSEC3 signing feature.
CVE-2010-0382 1 Isc 1 Bind 2025-04-11 7.6 HIGH N/A
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 handles out-of-bailiwick data accompanying a secure response without re-fetching from the original source, which allows remote attackers to have an unspecified impact via a crafted response, aka Bug 20819. NOTE: this vulnerability exists because of a regression during the fix for CVE-2009-4022.
CVE-2012-3570 1 Isc 1 Dhcp 2025-04-11 5.7 MEDIUM N/A
Buffer overflow in ISC DHCP 4.2.x before 4.2.4-P1, when DHCPv6 mode is enabled, allows remote attackers to cause a denial of service (segmentation fault and daemon exit) via a crafted client identifier parameter.
CVE-2012-3868 1 Isc 1 Bind 2025-04-11 4.3 MEDIUM N/A
Race condition in the ns_client structure management in ISC BIND 9.9.x before 9.9.1-P2 allows remote attackers to cause a denial of service (memory consumption or process exit) via a large volume of TCP queries.
CVE-2010-3611 1 Isc 1 Dhcp 2025-04-11 4.3 MEDIUM N/A
ISC DHCP server 4.0 before 4.0.2, 4.1 before 4.1.2, and 4.2 before 4.2.0-P1 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a DHCPv6 packet containing a Relay-Forward message without an address in the Relay-Forward link-address field.
CVE-2010-3616 1 Isc 1 Dhcp 2025-04-11 5.0 MEDIUM N/A
ISC DHCP server 4.2 before 4.2.0-P2, when configured to use failover partnerships, allows remote attackers to cause a denial of service (communications-interrupted state and DHCP client service loss) by connecting to a port that is only intended for a failover peer, as demonstrated by a Nagios check_tcp process check to TCP port 520.
CVE-2012-4244 1 Isc 1 Bind 2025-04-11 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.
