  <title>socat: Format string vulnerability</title>
  <synopsis>
    socat contains a format string vulnerability that can potentially lead to
    remote or local execution of arbitrary code with the privileges of the
    socat process.

  <background>
    <p>
    socat is a multipurpose bidirectional relay, similar to netcat.
    </p>

  <description>
    <p>
    socat contains a syslog() based format string vulnerablility in the
    '_msg()' function of 'error.c'. Exploitation of this bug is only
    possible when socat is run with the '-ly' option, causing it to log
    messages to syslog.
    </p>
  </description>
  <impact type="normal">
    <p>
    Remote exploitation is possible when socat is used as a HTTP proxy
    client and connects to a malicious server. Local privilege escalation
    can be achieved when socat listens on a UNIX domain socket. Potential
    execution of arbitrary code with the privileges of the socat process is
    possible with both local and remote exploitations.
    </p>
  </impact>
  <workaround>
    <p>
    Disable logging to syslog by not using the '-ly' option when starting
    socat.
    </p>
  </workaround>
  <resolution>
    <p>
    All socat users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-misc/socat-1.4.0.3"</code>
  </resolution>
