CVE-2019-10098: mod_rewrite configurations vulnerable to open redirect Severity: Low Vendor: The Apache Software Foundation Versions Affected: httpd 2.4.0 to 2.4.39 Description: Redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an an unexpected URL within the request URL.

home:pgajdos:apache-test:after looks good; there is just apache-rex/mod_authn_dbd-mysql which is however unrelated and happens even before and I need to investigate later. Packages submitted. I believe all fixed.
