A path traversal vulnerability exists in rsync. It stems from behavior enabled
by the `--inc-recursive` option, a default-enabled option for many client options
and can be enabled by the server even if not explicitly enabled by the client.
When using the `--inc-recursive` option, a lack of proper symlink verification
coupled with deduplication checks occurring on a per-file-list basis could allow
a server to write files outside of the client's intended destination directory.
A malicious server could write malicious files to arbitrary locations named after
valid directories/paths on the client.
