Comment 2 Joe Orton 2018-07-20 08:08:25 UTC
This issue was already addressed in current updates which upgraded mod_http2 to version 1.10.18 in Fedora, although the vulnerability (and the CVE name) were not public at the time.

Fedora does not use the version of mod_http2 bundled in the httpd sources.
