3proxy is a really tiny cross-platform proxy servers set, including
|
|
HTTP, HTTPS, FTP, SOCKS and POP3 support.

<description>
|
|
<p>
|
|
3proxy contains a double free vulnerability in the ftpprchild()
|
|
function, which frees param->hostname and calls the parsehostname()
|
|
function, which in turn attempts to free param->hostname again.
|
|

|
<impact type="normal">
|
|
<p>
|
|
A remote attacker could send a specially crafted request to the proxy,
|
|
possibly resulting in a Denial of Service. Under typical configuration,
|
|
the scope of this vulnerability is limited to the local network.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All 3proxy users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-proxy/3proxy-0.5.3j"</code>
|
