    The SSH Secure Shell Server from SSH Communications Security
    (www.ssh.com) is a commercial SSH implementation available free for
    non-commercial use.

  <description>
    <p>
    The SSH Secure Shell Server contains a format string vulnerability in
    the SFTP code that handles file transfers (scp2 and sftp2). In some
    situations, this code passes the accessed filename to the system log.
    During this operation, an unspecified error could allow uncontrolled
    stack access.
    </p>

  <impact type="normal">
    <p>
    An authenticated system user may be able to exploit this vulnerability
    to bypass command restrictions, or run commands as another user.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    This package is currently masked, there is no upgrade path for the
    3.2.x version, and a license must be purchased in order to update to a
    non-vulnerable version. Because of this, we recommend unmerging this
    package:
    </p>
    <code>
    # emerge --ask --verbose --unmerge net-misc/ssh</code>
