ISC DHCP 4.1 before 4.1.1-P1 and 4.0 before 4.0.2-P1 allows remote attackers to cause a denial of service (server exit) via a zero-length client ID.

Common Vulnerabilities and Exposures assigned an identifier CVE-2010-3611 to the following vulnerability:

Name: CVE-2010-3611 URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-3611 Assigned: 20100927 Reference: CONFIRM: http://www.isc.org/software/dhcp/advisories/cve-2010-3611 Reference: CERT-VN:VU#102047 Reference: URL: http://www.kb.cert.org/vuls/id/102047 Reference: BID:44615 Reference: URL: http://www.securityfocus.com/bid/44615 Reference: SECUNIA:42082 Reference: URL: http://secunia.com/advisories/42082 Reference: VUPEN:ADV-2010-2879 Reference: URL: http://www.vupen.com/english/advisories/2010/2879 Reference: XF:iscdhcp-relayforward-dos(62965) Reference: URL: http://xforce.iss.net/xforce/xfdb/62965

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 (crash) via a DHCPv6 packet containing a Relay-Forward message without an address in the Relay-Forward link-address field.

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.

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.

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.

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.
