Comment 12 Cedric Buissart 2020-02-20 13:34:13 UTC

Created rubygem-loofah tracking bugs for this issue:

Affects: fedora-all [bug 1805200]

Comment 13 Cedric Buissart 2020-02-20 13:52:44 UTC

Statement:

Supported versions of Satellite 6 contain a vulnerable version of rubygem-loofah. However, it is not possible to inject untrusted SVG files, and thus it is considered that this vulnerability can not be triggered. A future update may fix this vulnerability.
