Vulnerability Summary for CVE-2011-4868

Original release date: 01/14/2012
Last revised: 08/21/2013
Source: US-CERT/NIST

Overview

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.

Impact

CVSS Severity (version 2.0):
CVSS v2 Base Score: 6.1 MEDIUM
Impact Subscore: 6.9
Exploitability Subscore: 6.5
CVSS Version 2 Metrics:
Access Vector: Local network exploitable
Access Complexity: Low
Authentication: Not required to exploit
Impact Type: Allows disruption of service
