<title>rsync: Potential information leakage</title>
|
|
<synopsis>
|
|
rsync fails to properly sanitize paths. This vulnerability could allow the
|
|
listing of arbitrary files and allow file overwriting outside module's path
|
|
on rsync server configurations that allow uploading.

rsync is a utility that provides fast incremental file transfers. It is
|
|
used to efficiently synchronize files between hosts and is used by
|
|
emerge to fetch Gentoo's Portage tree. rsyncd is the rsync daemon,
|
|
which listens to connections from rsync clients.

|
<p>
|
|
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 type="normal">
|
|
<p>
|
|
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.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
You should never set the rsync daemon to run with "use chroot = false".
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All users should update to the latest version of the rsync package.
