<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 ">=net-misc/socat-1.4.0.3"</code>
|
|
