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

Parallel-ForkManager is a simple parallel processing fork manager for Perl.
The Perl Parallel-ForkManager module does not handle temporary files securely.
A local attacker could perform symlink attacks to overwrite arbitrary files with the privileges of the user running the application.
There is no known workaround at this time.
All Parallel-ForkManager users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-perl/Parallel-ForkManager-1.20.0"
