REPORT requests in mod_dav_svn, the Subversion component which is used
to serve repositories with the Apache web server. A remote attacker
could abuse this vulnerability for a denial of service.

We recommend that you upgrade your subversion packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
