Problem description

rsync is a widely spread protocol to mirror directory hierarchies.
An integer signedness bug causes the rsync daemon to mistreat data input from the network so that the process can be controlled by the remote user. By consequence, the remote user can trick the rsyncd process to execute arbitrary commands. This error is particularly dangerous for sites that offer anonymous (non-authorized) rsync service to the internet.
There is no temporary workaround against this problem other than this package update. Since rsyncd is usually started from inetd/xinetd, new instances of the daemon are lauched upon request. Therefore, it should not be necessary to kill all running instances of rsyncd after installation of the patch.
