This script is Copyright (C) 2008-2015 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-200810-03
(libspf2: DNS response buffer overflow)

libspf2 uses a fixed-length buffer to receive DNS responses and does
not properly check the length of TXT records, leading to buffer

Impact :

A remote attacker could store a specially crafted DNS entry and entice
a user or automated system using libspf2 to lookup that SPF entry (e.g.
by sending an email to the MTA), possibly allowing for the execution of
arbitrary code.

Workaround :

There is no known workaround at this time.

Solution :

# emerge --sync
# emerge --ask --oneshot --verbose '>=mail-filter/libspf2-1.2.8'
