Amazon Linux AMI : bind (ALAS-2015-594)

high Nessus Plugin ID 85752

Language:

Synopsis

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

Description

As discussed upstream, parsing a malformed DNSSEC key can cause a validating resolver to exit due to a failed assertion in buffer.c. It is possible for a remote attacker to deliberately trigger this condition, for example by using a query which requires a response from a zone containing a deliberately malformed key. (CVE-2015-5722)

Also disclosed upstream today was CVE-2015-5986 which does not impact the version of bind in the Amazon Linux AMI.

Solution

Run 'yum update bind' to update your system.
