"Several vulnerabilities were found in ViewVC, a web interface for CVS
and Subversion repositories.

  - CVE-2009-5024
    Remote attackers can bypass the cvsdb row_limit
    configuration setting, and consequently conduct
    resource-consumption attacks via the limit parameter.

  - CVE-2012-3356
    The remote Subversion views functionality does not
    properly perform authorization, which allows remote
    attackers to bypass intended access restrictions.

  - CVE-2012-3357
    The Subversion revision view does not properly handle
    log messages when a readable path is copied from an
    unreadable path, which allows remote attackers to obtain
    sensitive information.

  - CVE-2012-4533
    'function name' lines returned by diff are not properly
    escaped, allowing attackers with commit access to
    perform cross site scripting."
