[GLSA-200408-17] rsync: Potential information leakage Vulnerability Scan
Vulnerability Scan Summary
rsync: Potential information leakage
Detailed Explanation for this Vulnerability Test
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.
Impact
When rsyncd is used without chroot ("use chroot = false" in the
rsyncd.conf file), this vulnerability could allow the listing of arbitrary
files outside module's path and allow file overwriting outside module's
path on rsync server configurations that allows uploading. Both
possibilities are exposed only when chroot option is disabled.
Workaround
You should never set the rsync daemon to run with "use chroot =
false".
