+OpenPKG-SA-2004.031 08-Jul-2004

+
+Package: dhcpd
+Vulnerability: denial of service, arbitrary code execution
+OpenPKG Specific: no
+
+Affected Releases: Affected Packages: Corrected Packages:
+OpenPKG CURRENT <= dhcpd-3.0.1rc13-20040524 >= dhcpd-3.0.1rc14-20040623
+OpenPKG 2.0 <= dhcpd-3.0.1rc13-2.0.0 >= dhcpd-3.0.1rc13-2.0.1
+OpenPKG 1.3 <= dhcpd-3.0.1rc11-1.3.0 >= dhcpd-3.0.1rc11-1.3.1
+
+Affected Releases: Dependent Packages: none
+
+Description:
+ As reported by US-CERT [0] Gregory Duchemin discovered several
+ vulnerabilities in ISC DHCP Distribution [1] and helped fixing them.
+
+ Several buffer overflows were closed in logging messages with
+ excessively long hostnames provided by the clients. The Common
+ Vulnerabilities and Exposures (CVE) project assigned the id
+ CAN-2004-0460 [2] to the problem.
+
+ 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 bounds checking. The RELEASE
+ updates enforces use of the favorable functions as it was verified
+ they exist on all platforms supported by OpenPKG. The CURRENT update
+ contains a vendor fix explicitly providing a suitable function. The
+ Common Vulnerabilities and Exposures (CVE) project assigned the id
+ CAN-2004-0461 [3] to the problem.
+
+ Please check whether you are affected by running "<prefix>/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) and its dependent packages (see above), if any,
+ too [4][5].
+
+Solution:
+ Select the updated source RPM appropriate for your OpenPKG release
+ [6][7], fetch it from the OpenPKG FTP service [8][9] or a mirror
+ location, verify its integrity [10], build a corresponding binary RPM
+ from it [4] and update your OpenPKG installation by applying the
+ binary RPM [5]. For the most recent release OpenPKG 2.0, perform the
+ following operations to permanently fix the security problem (for
+ other releases adjust accordingly).
+
+ $ ftp ftp.openpkg.org
+ ftp> bin
+ ftp> cd release/2.0/UPD
+ ftp> get dhcpd-3.0.1rc13-2.0.1.src.rpm
+ ftp> bye
+ $ <prefix>/bin/openpkg rpm -v --checksig dhcpd-3.0.1rc13-2.0.1.src.rpm
+ $ <prefix>/bin/openpkg rpm --rebuild dhcpd-3.0.1rc13-2.0.1.src.rpm
+ $ su -
+ # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/dhcpd-3.0.1rc13-2.0.1.*.rpm
