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.
We recommend all users to upgrade to a known fixed release of the
Subversion server.
