    <p>
    rssh is a restricted shell, allowing only a few commands like scp or
    sftp. It is often used as a complement to OpenSSH to provide limited
    access to users.

  <description>
    <p>
    Florian Schilhabel from the Gentoo Linux Security Audit Team found a
    format string vulnerability in rssh syslogging of failed commands.
    </p>
  </description>
  <impact type="high">
    <p>
    Using a malicious command, it may be possible for a remote
    authenticated user to execute arbitrary code on the target machine with
    user rights, effectively bypassing any restriction of rssh.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All rssh users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-shells/rssh-2.2.2&quot;</code>
  </resolution>
