How to fix?

Upgrade Ubuntu:16.04 subversion to version 1.9.3-2ubuntu1.3+esm1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream subversion package and not the subversion package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 relevant fixed versions and status.

Subversion's mod_authz_svn module will crash if the server is using in-repository authz rules with the AuthzSVNReposRelativeAccessFile option and a client sends a request for a non-existing repository URL. This can lead to disruption for users of the service. This issue was fixed in mod_dav_svn+mod_authz_svn servers 1.14.1 and mod_dav_svn+mod_authz_svn servers 1.10.7
