"Several security issues have been found in the server components of
the version control system subversion.

  - CVE-2015-3184
    Subversion's mod_authz_svn does not properly restrict
    anonymous access in some mixed anonymous/authenticated
    environments when using Apache httpd 2.4. The result is
    that anonymous access may be possible to files for which
    only authenticated access should be possible. This issue
    does not affect the oldstable distribution (wheezy)
    because it only contains Apache httpd 2.2.

  - CVE-2015-3187
    Subversion servers, both httpd and svnserve, will reveal
    some paths that should be hidden by path-based authz.
    When a node is copied from an unreadable location to a
    readable location the unreadable path may be revealed.
    This vulnerablity only reveals the path, it does not
    reveal the contents of the path."
