Proxytunnel is a program that tunnels connections to a remote server
|
|
through a standard HTTPS proxy.

<p>
|
|
Florian Schilhabel of the Gentoo Linux Security Audit project found a
|
|
format string vulnerability in Proxytunnel. When the program is started in
|
|
daemon mode (-a [port]), it improperly logs invalid proxy answers to
|
|
syslog.
|
|
</p>

|

|
|
<impact type="normal">
|
|
<p>
|
|
A malicious remote server could send specially-crafted invalid answers to
|
|
exploit the format string vulnerability, potentially allowing the execution
|
|
of arbitrary code on the tunnelling host with the rights of the Proxytunnel
|
|
process.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
You can mitigate the issue by only allowing connections to trusted remote
|
|
servers.
|
|
</p>
|
|
</workaround>

|
<resolution>
|
|
<p>
|
|
All Proxytunnel users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-misc/proxytunnel-1.2.3"</code>
