    OpenPKG-SA-2004.026 27-May-2004
    ________________________________________________________________________

    Package: apache (option "with_mod_ssl" only)
    Vulnerability: arbitrary code execution
    OpenPKG Specific: no

    Affected Releases: Affected Packages: Corrected Packages:
    OpenPKG CURRENT <= apache-1.3.31-20040524 >= apache-1.3.31-20040527
    OpenPKG 2.0 <= apache-1.3.29-2.0.1 >= apache-1.3.29-2.0.2
    OpenPKG 1.3 <= apache-1.3.28-1.3.3 >= apache-1.3.28-1.3.4

    Dependent Packages: none

    Description:
      Georgi Guninski discovered [1] a stack-based buffer overflow in
      the "SSLOptions +FakeBasicAuth" implementation of Apache's SSL/TLS
      extension module mod_ssl [0]. The overflow can occur if the Subject-DN
      in the client certificate exceeds 6KB in length and mod_ssl is
      configured to trust the issuing CA. The Common Vulnerabilities and
      Exposures (CVE) project assigned the id CAN-2004-0488 [2] to the
      problem.

      Please check whether you are affected by running "<prefix>/bin/rpm -q
      apache" and "<prefix>/bin/rpm -qi apache | grep with_mod_ssl". If you
      have the "apache" package with option "with_mod_ssl" installed and its
      version is affected (see above), we recommend that you immediately
      upgrade (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 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 apache-1.3.29-2.0.2.src.rpm
      ftp> bye
      $ <prefix>/bin/openpkg rpm -v --checksig apache-1.3.29-2.0.2.src.rpm
      $ <prefix>/bin/openpkg rpm --rebuild --with mod_ssl apache-1.3.29-2.0.2.src.rpm
      $ su -
      # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/apache-1.3.29-2.0.2.*.rpm
