Echo: rsync: security update to 3.5.0

high Tenable Self-Hosted Container Security Plugin ID 459919

Description

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

 - rsync before 3.5.0 contains a symlink following vulnerability that allows local attackers to overwrite
 arbitrary files by placing a symlink at a predictable output path such as --log-file, --write-batch, or
 daemon-mode log and statistics paths. Attackers can exploit rsync's failure to reject symlinks during
 ancillary file writes to redirect output to arbitrary filesystem locations, achieving local privilege
 escalation on installations where rsync runs with elevated privileges such as setuid or privileged daemon
 configurations. (CVE-2026-53803)

Solution

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