Overview
The DHCP daemon (DHCPD) is a server that is used to allocate network addresses and assign configuration parameters to dynamically configured hosts. A format string vulnerability may permit an intruder to execute code with the privileges of the DHCP daemon (typically root).
Description
The Internet Software Consortium (ISC) produces a DHCP server. DHCPD listens for requests from client machines connecting to the network. Versions 3 to 3.0.1rc8 inclusive of DHCPD contain an option (NSUPDATE) that is compiled in by default. NSUPDATE allows the DHCP server to send an update to the DNS server after processing a DHCP request. The DNS server responds by sending a message back to the DHCP server. The response from the DNS server can contain user-supplied data. When this message is received, the DHCP server logs the transaction. A format string vulnerability exists in the DHCPD code that logs the transaction. This vulnerability may permit an attacker to execute code with the privileges of the DHCP daemon. |
Impact
A remote attacker can execute arbitrary code on the vulnerable host with the privileges of the DHCP server (DHCPD), typically root. |

Status
Affected
Vendor Statement
Following the recent CERT advisory on security vulnerabilities in the ISC DHCP implementation, Alcatel has conducted an immediate assessment to determine any impact this may have on our portfolio. A first analysis has shown that only one customer-specific product was affected. Alcatel is working with that customer on a solution. The security of our customers' networks is of highest priority for Alcatel. Therefore we continue to test our product portfolio against potential ISC DHCP security vulnerabilities and will provide updates if necessary.
