Package:             dhcpd
Vulnerability:       buffer overflows in minires library
OpenPKG Specific:    no

Affected Releases:   Affected Packages:          Corrected Packages:
OpenPKG CURRENT      <= dhcpd-3.0.1rc10-20021108 >= dhcpd-3.0.1rc11-20030116
OpenPKG 1.1          <= dhcpd-3.0.1rc9-1.1.0     >= dhcpd-3.0.1rc9-1.1.1
OpenPKG 1.0          <= dhcpd-3.0.1rc4-1.0.0     >= dhcpd-3.0.1rc4-1.0.1

Affected Releases:   Dependent Packages: none

Description:
  According to CERT advisory CA-2003-01 [0] a buffer overflow exists in
  the minires library embedded in ISC DHCPD versions 3.0 through
  3.0.1RC10 [1].  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 "<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). [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
  $ <prefix>/bin/rpm -v --checksig dhcpd-3.0.1rc9-1.1.1.src.rpm
  $ <prefix>/bin/rpm --rebuild dhcpd-3.0.1rc9-1.1.1.src.rpm
  $ su -
  # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/dhcpd-3.0.1rc9-1.1.1.*.rpm
