Echo: rsync: security update to 3.5.0

high Tenable Cloud Security Plugin ID 458532

Description

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

 - rsync before 3.5.0 contains an improper path handling vulnerability that allows a malicious sender to
 expand the scope of --delete operations beyond the intended destination subtree by sending a crafted file
 list that causes rsync to reclassify implied parent directory entries or treat synthetic paths as the
 transfer root. Attackers can exploit multiple variants including implied parent reclassification,
 synthetic root path construction, legacy protocol behavior below version 30, and non-directory root
 handling to cause the receiver to delete files outside the authorized destination directory.
 (CVE-2026-53789)

Solution

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