Package:             libtool
Vulnerability:       insecure creation of temporary directory
OpenPKG Specific:    no

Affected Releases:   Affected Packages:          Corrected Packages:
OpenPKG CURRENT      <= libtool-1.5.2-20040207   >= libtool-1.5.2-20040308
OpenPKG 2.0          <= libtool-1.5.2-2.0.0      >= libtool-1.5.2-2.0.1
OpenPKG 1.3          <= libtool-1.5-1.3.0        >= libtool-1.5-1.3.1

Dependent Packages:  none

Description:
  According to a posting on Bugtraq [0], an issue regarding the insecure
  creation of a temporary directory exists in GNU libtool [1] versions
  before 1.5.2. Use of mkdir(1) along with option "-p" makes libtool
  vulnerable to symlink attacks. Stefan Nordhausen commited a fix that
  removes the use of option "-p" in version 1.5.2. Discussion on Bugtraq
  further indicates that an additional race condition issue exists in
  the same context using chmod(1), reported by Joseph S. Myers back in
  March 2000 [2]. The updated OpenPKG versions of libtool contain fixes
  for both issues.

  Please check whether you are affected by running "<prefix>/bin/rpm -q
  libtool". If you have the "libtool" package 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], 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 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 libtool-1.5.2-2.0.1.src.rpm
  ftp> bye
  $ <prefix>/bin/openpkg rpm -v --checksig libtool-1.5.2-2.0.1.src.rpm
  $ <prefix>/bin/openpkg rpm --rebuild libtool-1.5.2-2.0.1.src.rpm
  $ su -
  # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/libtool-1.5.2-2.0.1.*.rpm
