Background

Graphviz is an open source graph visualization software.

Affected Packages

Package: media-gfx/graphviz
Vulnerable: < 2.20.3
Unaffected: >= 2.20.3
Architectures: All supported architectures

Workaround

There is no known workaround at this time.

Resolution

All Graphviz users should upgrade to the latest version:
