PACKAGE   : rsync
SUMMARY   : Fix for remote vulnerability

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.
