    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
