Echo: rsync: security update to 3.5.0

high Tenable Self-Hosted Container Security Plugin ID 464502

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - rsync before 3.5.0 contains a symlink race condition vulnerability in the sender's directory scanning
 logic that allows attackers to cause the sender to enumerate and transfer files outside the module root's
 intended subtree. Attackers who can create or manipulate symlinks in a path component of the scanned tree
 can replace a symlink with a directory entry pointing outside the module root between the lstat() call and
 the subsequent opendir() call, exposing files beyond the intended root in both daemon-mode and non-daemon
 sender-side scanning. (CVE-2026-53801)

Solution

Update the rsync library and its related packages to version 3.5.0 or later.
