Dependent Packages:  none

Description:
  Greuff of VOID.AT discovered various format string vulnerabilities in
  the error output handling routines of the Neon HTTP and WebDAV client
  library [1]. The Common Vulnerabilities and Exposures (CVE) project
  assigned the id CAN-2004-0179 [2] to the problem.

  Please check whether you are affected by running "/bin/rpm
  -q neon" (respectively for "subversion", "cadaver", "sitecopy" and
  "tla"). If you have one of the packages installed and its version is
  affected (see above), we recommend that you immediately upgrade it
  (see Solution) [3][4].

Solution:
  Select the updated source RPM appropriate for your OpenPKG release
  [5][6][7][8][9], fetch it from the OpenPKG FTP service [11][12] or
  a mirror location, verify its integrity [13], 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 neon-0.24.4-2.0.1.src.rpm
  ftp> bye
  $ /bin/openpkg rpm -v --checksig neon-0.24.4-2.0.1.src.rpm
  $ /bin/openpkg rpm --rebuild neon-0.24.4-2.0.1.src.rpm
  $ su -
  # /bin/openpkg rpm -Fvh /RPM/PKG/neon-0.24.4-2.0.1.*.rpm

  Additionally, perform similar steps for the "subversion", "cadaver",
  "sitecopy" and "tla" packages.
