Synopsis

The remote Red Hat host is missing a security update for rsync.

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2026:6390 advisory.

The rsync utility enables the users to copy and synchronize files locally or across a network.
Synchronization with rsync is fast because rsync only sends the differences in files over the network instead of sending whole files. The rsync utility is also used as a mirroring tool.

* rsync: Rsync: Out of bounds array access via negative index (CVE-2025-10158)
