DATE CVE VULNERABILITY TITLE RISK
2019-10-09 CVE-2018-5732 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in ISC Dhcp
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.

2016-03-09 CVE-2016-2774 Improper Input Validation vulnerability in multiple products
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.
7.1
2016-01-14 CVE-2015-8605 Improper Input Validation vulnerability in multiple products
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.

2012-09-14 CVE-2012-3955 Denial of Service vulnerability in ISC DHCP IPv6 Lease Expiration Handling
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.

2012-07-25 CVE-2012-3954 Resource Management Errors vulnerability in multiple products
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.

2012-07-25 CVE-2012-3571 Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in multiple products
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.

6.1
2012-01-15 CVE-2011-4868 Resource Management Errors vulnerability in ISC Dhcp
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.

2011-12-08 CVE-2011-4539 Improper Input Validation vulnerability in multiple products
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.
