CVE-2024-12088: Rsync: --safe-links option bypass leads to path traversal
First published: Thu Dec 05 2024(Updated: )
A flaw was found in rsync. When using the `--safe-links` option, rsync fails to properly verify if a symbolic link destination contains another symbolic link within it. This results in a path traversal vulnerability, which may lead to arbitrary file write outside the desired directory.
