+- Avoiding damage on flatbed scanners
+
+ Most flatbed scanners have no protection against exceeding the physical scan
+ area height. That is, if a scan is attempted with a height that exceeds the
+ height of the scan surface, the scanner begins making loud noises and the
+ scan mechanism may be damaged. Thus, if you hear such a noise, IMMEDIATELY
+ turn off the scanner.
+
+ Normally, the backend will ensure that the maximum scan height is not
+ exceeded. However, if your scanner model has not been tested yet this
+ safety-guard may not work. Please report errors like this to the author of
+ the backend or the sane-devel mailing list.
+
+- Security problems with saned (SANE network scanning daemon)
+
+ saned is not intended to be exposed to the internet or other non-trusted
+ networks. Make sure that access is limited by tcpwrappers and/or a firewall
+ setup. Don't depend only on saned's own authentification. Don't run saned
+ as root if it's not necessary. And do not install saned as setuid root.
+ Read man saned(8) for details.
