Package:             apache
Vulnerability:       arbitrary code execution
OpenPKG Specific:    no

Affected Releases:   Affected Packages:        Corrected Packages:
OpenPKG CURRENT      <= apache-1.3.32-20041028 >= apache-1.3.33-20041029
OpenPKG 2.2          <= apache-1.3.31-2.2.0    >= apache-1.3.31-2.2.1
OpenPKG 2.1          <= apache-1.3.31-2.1.5    >= apache-1.3.31-2.1.6
OpenPKG 2.0          <= apache-1.3.29-2.0.6    >= apache-1.3.29-2.0.7 (*)
                     (*) actually already end-of-life

Dependent Packages:  none

Description:
  According to a vendor announcement [1], a vulnerability exists in
  the Apache HTTP server [0], version 1.3. The problem is a potential
  buffer overflow in the "get_tag" function of Apache's SSI module
  "mod_include". It allows local users who can create SSI documents
  to execute arbitrary code as the Apache run-time user via SSI
  documents that trigger a content length calculation error. The
  Common Vulnerabilities and Exposures (CVE) project assigned the id
  CAN-2004-0940 [2] to the problem.

  Please check whether you are affected by running "<prefix>/bin/openpkg
  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 most recent release OpenPKG 2.2, perform the
  following operations to permanently fix the security problem (for
  other releases adjust accordingly).

  $ ftp ftp.openpkg.org
  ftp> bin
  ftp> cd release/2.2/UPD
  ftp> get apache-1.3.31-2.2.1.src.rpm
  ftp> bye
  $ <prefix>/bin/openpkg rpm -v --checksig apache-1.3.31-2.2.1.src.rpm
  $ <prefix>/bin/openpkg rpm --rebuild apache-1.3.31-2.2.1.src.rpm
  $ su -
  # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/apache-1.3.31-2.2.1.*.rpm
