Not vulnerable. This issue did not affect the versions of subversion as shipped with Red Hat Enterprise Linux 5, 6 and 7 as they did not include support for additional level of caching for the DAG nodes, which cause excessive memory use due to the cached nodes not being deallocated in a timely manner.
