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

high Tenable Cloud Security Plugin ID 461771

Description

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

 - Rsync version 3.4.2 and prior contain symlink race condition vulnerabilities in path-based system calls
 including chmod, lchown, utimes, rename, unlink, mkdir, symlink, mknod, link, rmdir, and lstat that allow
 local attackers to redirect operations to files outside the exported rsync module. Attackers with local
 filesystem access can exploit the timing window between path resolution and syscall execution by swapping
 symlinks to apply sender-supplied permissions, ownership, timestamps, or filenames to arbitrary files
 outside the intended module boundary on rsync daemons configured with 'use chroot = no'. (CVE-2026-43619)

Solution

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