+  <title>rsync: Directory traversal in rsync daemon</title>
+  <synopsis>
+    Under specific conditions, the rsync daemon is vulnerable to a directory
+    traversal allowing to write files outside a sync module.

+    <package name="net-misc/rsync" auto="yes" arch="*">

+  <background>
+    <p>
+    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>
+  </background>
+  <description>
+    <p>
+    When rsyncd is used without chroot ("use chroot = false" in the rsyncd.conf
+    file), the paths sent by the client are not checked thoroughly enough. If
+    rsyncd is used with read-write permissions ("read only = false"), this
+    vulnerability can be used to write files anywhere with the rights of the
+    rsyncd daemon. With default Gentoo installations, rsyncd runs in a chroot,
+    without write permissions and with the rights of the "nobody" user.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    On affected configurations and if the rsync daemon runs under a privileged
+    user, a remote client can exploit this vulnerability to completely
+    compromise the host.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    You should never set the rsync daemon to run with "use chroot = false". If
+    for some reason you have to run rsyncd without a chroot, then you should
+    not set "read only = false".
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All users should update to the latest version of the rsync package.
+    </p>
