Fix for CVE-2025-10158

Summary

Rsync uses a reliable algorithm to bring remote and host files into

sync very quickly. Rsync is fast because it just sends the differences

in the files over the network instead of sending the complete

files. Rsync is often used as a very powerful mirroring process or

just as a more capable replacement for the rcp command. A technical

report which describes the rsync algorithm is included in this

package.
