Subversion project reports:

    Subversion servers reveal 'copyfrom' paths that should be hidden according
    to configured path-based authorization (authz) rules.  When a node has been
    copied from a protected location, users with access to the copy can see the
    'copyfrom' path of the original.  This also reveals the fact that the node
    was copied.  Only the 'copyfrom' path is revealed; not its contents. Both
    httpd and svnserve servers are vulnerable.
  



    While looking up path-based authorization rules, mod_dav_svn servers
    may attempt to use memory which has already been freed.
