Package:             apache [with_mod_ssl=yes]
Vulnerability:       format string vulnerability
OpenPKG Specific:    no

Affected Releases:   Affected Packages:          Corrected Packages:
OpenPKG CURRENT      <= apache-1.3.31-20040714   >= apache-1.3.31-20040716
OpenPKG 2.1          <= apache-1.3.31-2.1.0      >= apache-1.3.31-2.1.1
OpenPKG 2.0          <= apache-1.3.29-2.0.3      >= apache-1.3.29-2.0.4
OpenPKG 1.3          <= apache-1.3.28-1.3.5      >= apache-1.3.28-1.3.6

Dependent Packages:  none

Description:
  Triggered by a report to Packet Storm [1] from Virulent, a format
  string vulnerability was found in mod_ssl [2], the Apache SSL/TLS
  interface to OpenSSL, version (up to and including) 2.8.18 for Apache
  1.3. The mod_ssl in Apache 2.x is not affected. The vulnerability
  could be exploitable if Apache is used as a proxy for HTTPS URLs and
  the attacker established a own specially prepared DNS and origin
  server environment.
  
  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-1.3.29-2.0.4.src.rpm
  ftp> bye
  $ <prefix>/bin/openpkg rpm -v --checksig apache-1.3.29-2.0.4.src.rpm
  $ <prefix>/bin/openpkg rpm --rebuild --with mod_ssl apache-1.3.29-2.0.4.src.rpm
  $ su -
  # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/apache-1.3.29-2.0.4.*.rpm
