The remote host is missing updates announced in advisory GLSA 200312-03.

To address this vulnerability, all Gentoo users should read GLSA-200312-02 and ensure that all systems are upgraded to a version of the Linux kernel without the do_brk() vulnerability, and upgrade to version 2.5.7 of rsync: # emerge sync # emerge -pv '>=net-misc/rsync-2.5.7' # emerge '>=net-misc/rsync-2.5.7' # emerge clean Review your /etc/rsync/rsyncd.conf configuration file ensure that the use chroot='no' command is commented out or removed, or change use chroot='no' to use chroot='yes'. Then, if necessary, restart rsyncd: # /etc/init.d/rsyncd restart http://www.securityspace.com/smysecure/catid.html?in=GLSA%20200312-03 http://rsync.samba.org/#security_dec03 http://security.gentoo.org/glsa/glsa-200312-02.xml http://security.gentoo.org/glsa/glsa-200312-01.xml

rsync contains a heap overflow vulnerability that can be used to execute arbitrary code.
