Vulnerability Assessment Details
rsync: Potential information leakage
Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200408-17
(rsync: Potential information leakage)
The paths sent by the rsync client are not checked thoroughly enough. It
does not affect the normal send/receive filenames that specify what files
should be transferred. It does affect certain option paths that cause
auxilliary files to be read or written.
When rsyncd is used without chroot ("use chroot = false" in the
rsyncd.conf file), this vulnerability could permit the listing of arbitrary
files outside module's path and permit file overwriting outside module's
path on rsync server configurations that permits uploading. Both
possibilities are exposed only when chroot option is disabled.
You should never set the rsync daemon to run with "use chroot =
All users should update to the latest version of the rsync package.
