(Subversion: Metadata information leak)

    There is a bug in mod_authz_svn that causes it to reveal logged metadata
    regarding commits to protected areas.
  
Impact :

    Protected files themselves will not be revealed, but an attacker could use
    the metadata to reveal the existence of protected areas, such as paths,
    file versions, and the commit logs from those areas.
  
Workaround :

    Rather than using mod_authz_svn, move protected areas into separate
    repositories and use native Apache authentication to make these
    repositories unreadable."
