    Package: apache
    Vulnerability: local buffer overflow
    OpenPKG Specific: no

    Affected Releases: Affected Packages: Corrected Packages:
    OpenPKG CURRENT <= apache-1.3.28-20031009 >= apache-1.3.29-20031028
    OpenPKG 1.3 <= apache-1.3.28-1.3.0 >= apache-1.3.28-1.3.1
    OpenPKG 1.2 <= apache-1.3.27-1.2.2 >= apache-1.3.27-1.2.3

    Dependent Packages: none

    Description:
      André Malo discovered buffer overflows [0] in the mod_alias and
      mod_rewrite modules of the Apache [1] webserver. These occurred if
      a regular expression with more than 9 capturing parenthesis was
      configured. To exploit this, an attacker would need to be able to
      locally create a carefully crafted configuration file (.htaccess or
      httpd.conf). The Common Vulnerabilities and Exposures (CVE) project
      assigned the id CAN-2003-0542 [2] to the problem.

      Please check whether you are affected by running "<prefix>/bin/rpm -q
      apache". If you have the "apache" 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 1.3, perform the
      following operations to permanently fix the security problem (for
      other releases adjust accordingly).

      $ ftp ftp.openpkg.org
      ftp> bin
      ftp> cd release/1.3/UPD
      ftp> get apache-1.3.28-1.3.1.src.rpm
      ftp> bye
      $ <prefix>/bin/rpm -v --checksig apache-1.3.28-1.3.1.src.rpm
      $ <prefix>/bin/rpm --rebuild apache-1.3.28-1.3.1.src.rpm
      $ su -
      # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/apache-1.3.28-1.3.1.*.rpm
