________________________________________________________________________

Package:             apache
Vulnerability:       remote DoS / exploit
OpenPKG Specific:    no

Affected  Releases:  OpenPKG 1.0 
Affected  Packages:  <= apache-1.3.22-1.0.1
Corrected Packages:  >= apache-1.3.22-1.0.2
Dependent Packages:  -

Description:
  According to a Security Bulletin from the Apache Software Foundation
  [5] and a corresponding CERT Security Advisory [6], there is a
  remotely exploitable vulnerability in the way that the Apache web
  server handles data encoded in chunks. This bug can be triggered
  remotely by sending a carefully crafted invalid request. This
  functionality is enabled by default.

  Please check whether you are affected by running "<prefix>/bin/rpm -qa
  apache". If you have the "apache" package installed and its version
  is affected (see above), we recommend that you immediately upgrade it
  (see Solution).

Solution:
  Select the updated source RPM appropriate for your OpenPKG release
  [4], fetch it from the OpenPKG FTP service [3] or a mirror
  location, verify its integrity [1], build a corresponding binary RPM
  from it and update your OpenPKG installation by applying the binary
  RPM [2]. For the latest OpenPKG 1.0 release, perform the following
  operations to permanently fix the security problem (for other releases
  adjust accordingly).

  $ ftp ftp.openpkg.org
  ftp> bin
  ftp> cd release/1.0/UPD
  ftp> get apache-1.3.22-1.0.2.src.rpm
  ftp> bye
  $ <prefix>/bin/rpm --checksig apache-1.3.22-1.0.2.src.rpm
  $ <prefix>/bin/rpm --rebuild apache-1.3.22-1.0.2.src.rpm
  $ su -
  # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/apache-1.3.22-1.0.2.*.rpm
  # <prefix>/etc/rc apache stop start
