OpenPKG Security Advisory                            The OpenPKG Project

Vulnerability:       arbitrary code execution
OpenPKG Specific:    no

Affected Releases:   Affected Packages:          Corrected Packages:

  According to a security advisory from Ulf Härnhammar [0], a buffer
  overflow bug exists in the FTP/HTTP/HTTPS client LFTP [1] bug in
  versions up to and including 2.6.9. An attacker could create a
  carefully crafted directory on a website such that, if a user connects
  to that directory using the LFTP client and subsequently issues a "ls"
  or "rels" command, the attacker could execute arbitrary code on the
  users machine. The Common Vulnerabilities and Exposures (CVE) project
  assigned the id CAN-2003-0963 [2] to the problem.

  Please check whether you are affected by running "/bin/rpm -q
  lftp". If you have the "lftp" package installed and its version is
  affected (see above), we recommend that you immediately upgrade it
  (see Solution) [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 current release OpenPKG 1.3, perform the following
  operations to permanently fix the security problem (for other releases
  adjust accordingly).

  $ ftp
  ftp> bin
  ftp> cd release/1.3/UPD
  ftp> get lftp-2.6.6-1.3.1.src.rpm
  ftp> bye
  $ /bin/rpm -v --checksig lftp-2.6.6-1.3.1.src.rpm
  $ /bin/rpm --rebuild lftp-2.6.6-1.3.1.src.rpm
  $ su -
  # /bin/rpm -Fvh /RPM/PKG/lftp-2.6.6-1.3.1.*.rpm
