Amazon Linux AMI : bind (ALAS-2021-1485)

high Nessus Plugin ID 147916

Language:

Synopsis

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

Description

The version of bind installed on the remote host is prior to 9.8.2-0.68.rc1.86. It is, therefore, affected by a vulnerability as referenced in the ALAS-2021-1485 advisory.

 A buffer overflow flaw was found in the SPNEGO implementation used by BIND. This flaw allows a remote attacker to cause the named process to crash or possibly perform remote code execution. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2020-8625)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update bind' to update your system.
