Amazon Linux AMI : bind (ALAS-2015-631)

Medium Nessus Plugin ID 87380

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

An error in the parsing of incoming responses allows some records with an incorrect class to be be accepted by BIND instead of being rejected as malformed. This can trigger a REQUIRE assertion failure when those records are subsequently cached. Intentional exploitation of this condition is possible and could be used as a denial-of-service vector against servers performing recursive queries. (CVE-2015-8000)

CVE-2015-8461 was also issued today for bind, but the Amazon Linux AMI's version of bind is not impacted by that CVE.

Solution

Run 'yum update bind' to update your system.
