| CVE-2018-5732 |
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 Published: October 09, 2019; 12:15:13 PM -0400 |
V3.1: 7.5 HIGH V2.0: 5.0 MEDIUM |
| CVE-2016-2774 |
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.

V3.1: 5.9 MEDIUM V2.0: 7.1 HIGH |
| CVE-2015-8605 |
ISC DHCP 4.x before 4.1-ESV-R12-P1, 4.2.x, and 4.3.x before 4.3.3-P1 allows remote attackers to cause a denial of service (application crash) via an invalid length field in a UDP IPv4 packet. Published: January 14, 2016; 5:59:00 PM -0500 |
V3.0: 6.5 MEDIUM V2.0: 5.7 MEDIUM |
| CVE-2012-3955 |
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. Published: September 14, 2012; 6:33:21 AM -0400 |
V3.x:(not available) V2.0: 7.1 HIGH |
| CVE-2012-3954 |
Multiple memory leaks in ISC DHCP 4.1.x and 4.2.x before 4.2.4-P1 and 4.1-ESV before 4.1-ESV-R6 allow remote attackers to cause a denial of service (memory consumption) by sending many requests. Published: July 25, 2012; 6:42:35 AM -0400 |
V3.x:(not available) V2.0: 3.3 LOW |
| CVE-2012-3571 |
ISC DHCP 4.1.2 through 4.2.4 and 4.1-ESV before 4.1-ESV-R6 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a malformed client identifier. Published: July 25, 2012; 6:42:35 AM -0400 |
V3.x:(not available) V2.0: 6.1 MEDIUM |
| CVE-2011-4868 |
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. Published: January 14, 2012; 10:55:12 PM -0500 |
V3.x:(not available) V2.0: 6.1 MEDIUM |
| CVE-2011-4539 |
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. Published: December 08, 2011; 6:55:02 AM -0500 |
V3.x:(not available) V2.0: 5.0 MEDIUM |
| CVE-2011-2749 |
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 BOOTP packet. Published: August 15, 2011; 5:55:02 PM -0400 |
V3.x:(not available) V2.0: 7.8 HIGH |
| CVE-2011-2748 |
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. Published: August 15, 2011; 5:55:02 PM -0400 |
