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
    -------------------------------------------------------------------

                                  < 1.20.0                  >= 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
