Title: Microsoft Windows DHCP Server Remote Buffer Overflow Vulnerability
Severity: CRITICAL
Description:
Certain Microsoft Windows operating systems contain a DHCP (Dynamic Host Configuration Protocol) server. This server is responsible for configuring the network settings of computers and other network devices in a LAN environment.
Microsoft Windows DHCP server on NT 4 server platforms is reported susceptible to a remote buffer overflow vulnerability. This issue is due to a failure of the application to properly bounds check the length of user-supplied network data prior to copying it to a fixed-size memory buffer.
Due to the use of UDP datagrams, exploitation attempts may originate from spoofed source addresses.
This vulnerability allows remote attackers to crash the affected service, denying service to legitimate users. This may allow attackers to interrupt network services to an entire network.
It is noted that the service is not installed by default.
