Subject Name:            DHCPd
Subject Summary:         DHCP Daemon
Subject Home:            http://www.isc.org/products/DHCP/
Subject Versions:        * <= 3.0.1rc13

Vulnerability Id:        CVE-2004-0460, CVE-2004-0461
Vulnerability Scope:     global (not OpenPKG specific)

Attack Feasibility:      run-time
Attack Vector:           remote network
Attack Impact:           denial of service, arbitrary code execution

Description:
    As reported by US-CERT [0] Gregory Duchemin discovered several
    vulnerabilities in the ISC DHCP Distribution [1].
    
    Several buffer overflows were closed in logging messages with
    excessively long hostnames provided by the clients. CVE-2004-0460
    
    Another issue was evident on some specific platforms where the dhcpd
    build mechanism ignored the existence of [v]snprintf(3) functions
    and used the weaker [v]sprintf(3) which lack boundary checking. The
    RELEASE updates enforce use of the favorable functions after it was
    verified they exist on all platforms supported by OpenPKG. The CURRENT
    update contains a vendor fix explicitly providing a suitable function.
    CVE-2004-0461
