Comment 1 Sam Fowler 2018-07-03 04:52:57 UTC

Created pdfbox tracking bugs for this issue:

Affects: fedora-all [bug 1597491]

Comment 3 Hooman Broujerdi 2018-07-31 05:36:00 UTC

Statement:

While Fuse 6.3 and Fuse 7.0 ship vulnerable artifact via camel-pdfbox, however, the flawed code is not being used therefore no execution path leads to an exposure to this vulnerability, so both Fuse 6.3, 7 standalone are not affected. However, Fuse 7.0 on OpenShift ship vulnerable artifact via maven BOM, so setting Fuse 7.0 as affected for this reason only.

Comment 5 errata-xmlrpc 2018-09-11 07:57:52 UTC
