Amazon Linux AMI : bind (ALAS-2016-665)

high Nessus Plugin ID 89846

Synopsis

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

Description

A defect in control channel input handling was discovered which can cause named to exit due to an assertion failure in sexpr.c or alist.c when a malformed packet is sent to named's control channel. If control channel input is accepted from the network (limited to localhost by default), an unauthenticated attacker could cause named to crash.
(CVE-2016-1285)

An error when parsing signature records for DNAME records having specific properties can lead to named exiting due to an assertion failure in resolver.c or db.c. An attacker able to cause a server to make a query deliberately chosen to generate a malicious response can cause named to stop execution with an assertion failure, resulting in denial of service to clients. (CVE-2016-1286)

Solution

Run 'yum update bind' to update your system.
