The remote host is missing updates announced in advisory GLSA 200807-08.

All BIND users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose '>=net-dns/bind-9.4.2_p1' Note: In order to utilize the query port randomization to mitigate the weakness, you need to make sure that your network setup allows the DNS server to use random source ports for query and that you have not set a fixed query port via the 'query-source port' directive in the BIND configuration. http://www.securityspace.com/smysecure/catid.html?in=GLSA%20200807-08 http://bugs.gentoo.org/show_bug.cgi?id=231201

A weakness in the DNS protocol has been reported, which could lead to cache poisoning on recursive resolvers.
