Echo: rsync: security update to 3.5.0+ds1-1

medium Tenable Cloud Security Plugin ID 457744

Description

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

 - rsync before 3.5.0 contains a time-of-check to time-of-use (TOCTOU) race condition vulnerability in the
 non-daemon receiver's destination directory handling that allows an attacker who can manipulate
 destination path parent components to redirect file writes to unintended locations. Attackers can
 substitute a symlink for a component of the destination path between the path resolution and chdir() call,
 causing the receiver's working directory to be established outside the intended destination tree so that
 subsequent relative-path file writes land in unintended filesystem locations. (CVE-2026-53796)

Solution

Update the rsync library and its related packages to version 3.5.0+ds1-1 or later.
