Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200711-13
(3proxy: Denial of Service)

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 :

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.

Workaround :

There is no known workaround at this time.
