    Description:
      An integer overflow problem was discovered in the Perl Compatible
      Regular Expressions (PCRE) [1] library, version 6.2 and earlier.
      The problem allows a remote or local attacker to execute arbitrary
      code by causing a heap-based buffer overflow via quantifier values
      in regular expressions. As PCRE is a popular library, this problem
      affects many applications. The Common Vulnerabilities and Exposures
      (CVE) project assigned the id CAN-2005-2491 [2] to the problem.

      Please check whether you are affected by running "<prefix>/bin/openpkg
      rpm -q pcre". If you have the "pcre" package installed and its version
      is affected (see above), we recommend that you immediately upgrade it
      (see Solution) and its dependent packages (see above), too [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 2.4, perform the
      following operations to permanently fix the security problem (for
      other releases adjust accordingly).

      $ ftp ftp.openpkg.org
      ftp> bin
      ftp> cd release/2.4/UPD
      ftp> get pcre-6.0-2.4.1.src.rpm
      ftp> bye
      $ <prefix>/bin/openpkg rpm -v --checksig pcre-6.0-2.4.1.src.rpm
      $ <prefix>/bin/openpkg rpm --rebuild pcre-6.0-2.4.1.src.rpm
      $ su -
      # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/pcre-6.0-2.4.1.*.rpm

      Additionally, we recommend that you rebuild and reinstall
      all dependent packages (see above), too [3][4].
