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.

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

Resolution

All Parallel-ForkManager users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot -v ">=dev-perl/Parallel-ForkManager-1.20.0"
