Background

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

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 --verbose
 "&gt;=dev-perl/Parallel-ForkManager-1.20.0"
