+ Proxytunnel is vulnerable to a format string vulnerability, potentially
+ allowing a remote server to execute arbitrary code with the rights of the
+ Proxytunnel process.

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

+ <description>
+ <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>
+ </description>
+ <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 "&gt;=net-misc/proxytunnel-1.2.3"</code>
