CVE-2007-0062 has a CVSS v2 base score of 10.0 (the maximum on that scale) and affects VMware Ace. Per its scoring, it can be exploited over the network, without authentication. The scored impact on confidentiality, integrity and availability is the highest available.

Vulnerability description

Integer overflow in the ISC dhcpd 3.0.x before 3.0.7 and 3.1.x before 3.1.1; and the DHCP server in EMC VMware Workstation before 5.5.5 Build 56455 and 6.x before 6.0.1 Build 55017, Player before 1.0.5 Build 56455 and Player 2 before 2.0.1 Build 55017, ACE before 1.0.3 Build 54075 and ACE 2 before 2.0.1 Build 55017, and Server before 1.0.4 Build 56528; allows remote attackers to cause a denial of service (daemon crash) or execute arbitrary code via a malformed DHCP packet with a large dhcp-max-message-size that triggers a stack-based buffer overflow, related to servers configured to send many DHCP options to clients.
