Amazon Linux 2 : aws-kinesis-agent (ALAS-2021-1733)

medium Nessus Plugin ID 156263

Synopsis

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

Description

The version of aws-kinesis-agent installed on the remote host is prior to 2.0.5-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2021-1733 advisory.

- Apache Log4j2 versions 2.0-alpha1 through 2.16.0 (excluding 2.12.3) did not protect from uncontrolled recursion from self-referential lookups. This allows an attacker with control over Thread Context Map data to cause a denial of service when a crafted string is interpreted. This issue was fixed in Log4j 2.17.0 and 2.12.3. (CVE-2021-45105)

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 aws-kinesis-agent' to update your system.
