GLSA-200407-01 : Esearch: Insecure temp file handling

This script is Copyright (C) 2004-2015 Tenable Network Security, Inc.

Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200407-01
(Esearch: Insecure temp file handling)

The eupdatedb utility uses a temporary file (/tmp/ to
indicate that the eupdatedb process is running. When run, eupdatedb
checks to see if this file exists, but it does not check to see if it
is a broken symlink. In the event that the file is a broken symlink,
the script will create the file pointed to by the symlink, instead of
printing an error and exiting.

Impact :

An attacker could create a symlink from /tmp/ to a
nonexistent file (such as /etc/nologin), and the file will be created
the next time esearchdb is run.

Workaround :

There is no known workaround at this time. All users should upgrade to
the latest available version of esearch.

Solution :
