DESCRIPTION
"rsync"[1] is a program used mainly to mirror files between remote
sites.

rsync versions prior to 2.5.7 have a heap buffer overflow
vulnerability[2] which can be exploited by remote attackers to
execute arbitrary code.

This vulnerability specially affects installations where rsync is
used as a server/daemon, that is, where it was started with the
--daemon command line argument.

A new rsync version, 2.5.7, was released by the authors to address
this vulnerability.



SOLUTION
It is recommended that all rsync users upgrade their packages.

IMPORTANT: after the update, the rsync server must be restarted
manually if it was already running.
