Debian Security Advisory DSA-106-1 security@debian.org

Package : rsync
Problem type : remote exploit
Debian-specific: no
Sebastian Krahmer found several places in rsync (a popular tool to
synchronise files between machines) where signed and unsigned numbers
were mixed which resulted in insecure code. This could be abused by
remote users to write 0-bytes in rsync's memory and trick rsync into
executing arbitrary code.
This has been fixed in version 2.3.2-1.3 and we recommend you upgrade
your rsync package immediately.
wget url
will fetch the file for you
dpkg -i file.deb

upgrade to that version immediately.
