Package:             perl
Vulnerability:       information disclosure, insecure permissions
OpenPKG Specific:    no

Affected Releases:   Affected Packages:          Corrected Packages:
OpenPKG CURRENT      <= perl-5.8.6-20041129      >= perl-5.8.6-20050111
OpenPKG 2.2          <= perl-5.8.5-2.2.0         >= perl-5.8.5-2.2.1
OpenPKG 2.1          <= perl-5.8.4-2.1.0         >= perl-5.8.4-2.1.1

Dependent Packages:  none

Description:
  Jeroen van Wolffelaar discovered that the rmtree() function in the
  Perl [0] File::Path module removes directory trees in an insecure
  manner which could lead to the removal of arbitrary files and
  directories through a symlink attack. The Common Vulnerabilities and
  Exposures (CVE) project assigned the id CAN-2004-0452 [1] to the
  problem.

  Trustix developers discovered several insecure uses of temporary files
  in many modules which allow a local attacker to overwrite files via a
  symlink attack. The Common Vulnerabilities and Exposures (CVE) project
  assigned the id CAN-2004-0976 [2] to the problem.

  Please check whether you are affected by running "<prefix>/bin/openpkg
  rpm -q perl". If you have the "perl" 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 most recent release OpenPKG 2.2, perform the
  following operations to permanently fix the security problem (for
  other releases adjust accordingly).

  $ ftp ftp.openpkg.org
  ftp> bin
  ftp> cd release/2.2/UPD
  ftp> get perl-5.8.5-2.2.1.src.rpm
  ftp> bye
  $ <prefix>/bin/openpkg rpm -v --checksig perl-5.8.5-2.2.1.src.rpm
  $ <prefix>/bin/openpkg rpm --rebuild perl-5.8.5-2.2.1.src.rpm
  $ su -
  # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/perl-5.8.5-2.2.1.*.rpm
