Echo: rsync: security update to 3.4.1+ds1-5+deb13u3

high Tenable Self-Hosted Container Security Plugin ID 464222

Description

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

 - Rsync versions before 3.4.3 contain a time-of-check to time-of-use (TOCTOU) race condition in daemon file
 handling that allows attackers to redirect file writes outside intended directories by replacing parent
 directory components with symbolic links. Attackers with write access to a module path can exploit this
 race condition to create or overwrite arbitrary files, potentially modifying sensitive system files and
 achieving privilege escalation when the daemon runs with elevated privileges. This vulnerability can only
 be triggered if the chroot setting is false. (CVE-2026-29518)

Solution

Update the rsync library and its related packages to version 3.4.1+ds1-5+deb13u3 or later.
