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. | 5.0 |
2019-01-16 | CVE-2018-5733 | Integer Overflow or Wraparound vulnerability in multiple products A malicious client which is allowed to send very large amounts of traffic (billions of packets) to a DHCP server can eventually overflow a 32-bit reference counter, potentially causing dhcpd to crash. | 5.0 |
2019-01-16 | CVE-2017-3144 | Resource Exhaustion vulnerability in multiple products A vulnerability stemming from failure to properly clean up closed OMAPI connections can lead to exhaustion of the pool of socket descriptors available to the DHCP server. | 5.0 |
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. | 5.7 |
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. | 7.1 |
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. | 3.3 |
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. | 6.1 |
2011-08-15 | CVE-2011-2749 | Improper Input Validation vulnerability in multiple products 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. | 7.8 |
2011-08-15 | CVE-2011-2748 | Improper Input Validation vulnerability in multiple products 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. | 7.8 |
