Vulnerability Title
Rsync: --safe-links option bypass leads to path traversal
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in rsync. When using the `--safe-links` option, the rsync client fails to properly verify if a symbolic link destination sent from the server contains another symbolic link within it. This results in a path traversal vulnerability, which may lead to arbitrary file write outside the desired directory.
