Update
=====
The rmtree race conditions were only partly fixed in the original GLSA.
New versions of dev-lang/perl have been released to address the
remaining issues (CAN-2005-0448).

The updated sections appear below.

Affected packages
================
    -------------------------------------------------------------------
     Package        /   Vulnerable   /                      Unaffected

                                                            >= 1.38-r1
  2  dev-lang/perl      <= 5.8.6-r3                        >= 5.8.6-r4

                                                          *>= 5.8.4-r4
                                                          *>= 5.8.2-r4
    -------------------------------------------------------------------
     2 affected packages on all of their supported architectures.
    -------------------------------------------------------------------

Description
==========
Javier Fernandez-Sanguino Pena discovered that the DBI library creates
temporary files in an insecure, predictable way (CAN-2005-0077). Paul
Szabo found out that "File::Path::rmtree" is vulnerable to various race
conditions (CAN-2004-0452, CAN-2005-0448).

Impact
=====
A local attacker could create symbolic links in the temporary files
directory that point to a valid file somewhere on the filesystem. When
the DBI library or File::Path::rmtree is executed, this could be used
to overwrite or remove files with the rights of the user calling these
functions.

Resolution
=========
All Perl users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose dev-lang/perl

All DBI library users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose dev-perl/DBI
