Synopsis
========

An insecure temporary file usage has been reported in the Perl
Parallel-ForkManager module, possibly allowing symlink attacks.

Background
==========

Parallel-ForkManager is a simple parallel processing fork manager for
Perl.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-perl/Parallel-ForkManager
                                  < 1.20.0                  >= 1.20.0

Description
===========

The Perl Parallel-ForkManager module does not handle temporary files
securely.

Impact
======

A local attacker could perform symlink attacks to overwrite arbitrary
files with the privileges of the user running the application.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Parallel-ForkManager users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=dev-perl/Parallel-ForkManager-1.20.0"

References
==========
