There is no fixed version for RHEL:7 fop.

NVD Description

Note: Versions mentioned in the description apply only to the upstream fop package and not the fop package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

In Apache FOP before 2.2, files lying on the filesystem of the server which uses FOP can be revealed to arbitrary users who send maliciously formed SVG files. The file types that can be shown depend on the user context in which the exploitable application is running. If the user is root a full compromise of the server - including confidential or sensitive files - would be possible. XXE can also be used to attack the availability of the server via denial of service as the references within a xml document can trivially trigger an amplification attack.
