Amazon Linux 2 : bind (ALAS-2019-1170)

high Nessus Plugin ID 122676

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

Crash from assertion error when debug log level is 10 and log entries meet buffer boundary. This flaw appears to be exploitable only when debug logging is enabled and set to at least a level of 10. As this configuration should be rare in production instances of bind, it is unlikely that most servers will be exploitable. The debug level of the bind server can be checked via the rndc status command, which will return the current trace level as 'debug level'. A value of 10 or above would most likely make this flaw exploitable.(CVE-2018-5742)

Solution

Run 'yum update bind' to update your system.
