    Synopsis
    ========

    An information leak in mod_authz_svn could allow sensitive metadata of
    protected areas to be leaked to unauthorized users.

    Background
    ==========

    Subversion is a versioning system designed to be a replacement for CVS.
    mod_authz_svn is an Apache module to do path-based authentication for
    Subversion repositories.

    Affected packages
    =================

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 dev-util/subversion < 1.0.8 >= 1.0.8

    Description
    ===========

    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 seperate
    repositories and use native Apache authentication to make these
    repositories unreadable.

    Resolution
    ==========

    All Subversion users should upgrade to the latest version:

        # emerge sync

        # emerge -pv ">=dev-util/subversion-1.0.8"
        # emerge ">=dev-util/subversion-1.0.8"
