medium Nessus Plugin ID 27848

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.

Solution

All 3proxy users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-proxy/3proxy-0.5.3j'
