Synopsis

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

Description

The version of rsync installed on the remote host is prior to 3.1.2-11. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2074 advisory.

A security vulnerability was found in zlib. The flaw triggered a heap-based buffer in inflate in the inflate.c function via a large gzip header extra field. This flaw is only applicable in the call inflateGetHeader. (CVE-2022-37434)

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 rsync' to update your system.
