Background

DUMB (Dynamic Universal Music Bibliotheque) is an IT, XM, S3M and MOD player library.

Affected Packages

Package: media-libs/dumb
Vulnerable: < 0.9.3-r1
Unaffected: >= 0.9.3-r1
Architectures: All supported architectures

Workaround

There is no known workaround at this time.

Resolution

All users of DUMB should upgrade to the latest version:
