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.

Mitigation

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."
