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
A null-pointer-dereference flaw was found in mod_authz_svn of subversion. This flaw allows a remote, unauthenticated attacker to cause a denial of service in some server configurations. The highest threat from this vulnerability is to system availability.

As per upstream "As a workaround, the use of in-repository authz rules files with the AuthzSVNReposRelativeAccessFile can be avoided by switching to an alternative configuration which fetches an authz rules file from the server's filesystem, rather than from an SVN repository."
