  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].

  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].
