Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.
Closing this CVE tracker as it has been marked as rejected. See https://bugzilla.redhat.com/show_bug.cgi?id=2438909#c2 As noted there, this is an application bug and not a security issue. Additionally, this bug is not regarded as critical, as most GDB users are unlikely to encounter it. The fix will migrate from upstream to Fedora GDB via eventual rebases to upstream sources containing it.
