<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>
</background>
<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 &quot;&gt;=net-misc/socat-1.4.0.3&quot;</code>
</resolution>
