The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2003-0026 [2] to the problem. Please check whether you are affected by running "/bin/rpm -q dhcpd". If you have the "dhcpd" package installed and its version is affected (see above), we recommend that you immediately upgrade it (see Solution). [3][4] Solution: Select the updated source RPM appropriate for your OpenPKG release [5][6], fetch it from the OpenPKG FTP service [7][8] or a mirror location, verify its integrity [9], build a corresponding binary RPM from it [3] and update your OpenPKG installation by applying the binary RPM [4]. For the current release OpenPKG 1.1, perform the following operations to permanently fix the security problem (for other releases adjust accordingly). $ ftp ftp.openpkg.org ftp> bin ftp> cd release/1.1/UPD ftp> get dhcpd-3.0.1rc9-1.1.1.src.rpm ftp> bye $ /bin/rpm -v --checksig dhcpd-3.0.1rc9-1.1.1.src.rpm $ /bin/rpm --rebuild dhcpd-3.0.1rc9-1.1.1.src.rpm $ su - # /bin/rpm -Fvh /RPM/PKG/dhcpd-3.0.1rc9-1.1.1.*.rpm ________________________________________________________________________ References: [0] http://www.cert.org/advisories/CA-2003-01.html [1] http://www.isc.org/products/DHCP/dhcp-v3.html [2] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0026 [3] http://www.openpkg.org/tutorial.html#regular-source [4] http://www.openpkg.org/tutorial.html#regular-binary [5] ftp://ftp.openpkg.org/release/1.0/UPD/dhcpd-3.0.1rc4-1.0.1.src.rpm [6] ftp://ftp.openpkg.org/release/1.1/UPD/dhcpd-3.0.1rc9-1.1.1.src.rpm [7] ftp://ftp.openpkg.org/release/1.0/UPD/ [8] ftp://ftp.openpkg.org/release/1.1/UPD/ [9] http://www.openpkg.org/security.html#signature ________________________________________________________________________ For security reasons, this advisory was digitally signed with the OpenPGP public key "OpenPKG " (ID 63C4CB9F) of the OpenPKG project which you can find under the official URL http://www.openpkg.org/openpkg.pgp or on http://keyserver.pgp.com/.
