Amazon Linux 2023 : rsync, rsync-daemon (ALAS2023-2025-1302)

medium Nessus Plugin ID 277819

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2025-1302 advisory.

A malicious client acting as the receiver of an rsync file transfer can trigger an out of bounds read of a heap based buffer, via a negative array index. The malicious rsync client requires at least read access to the remote rsync module in order to trigger the issue. (CVE-2025-10158)

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 'dnf update rsync --releasever 2023.9.20251208' or or 'dnf update --advisory ALAS2023-2025-1302 --releasever 2023.9.20251208' to update your system.
