Description Mark J. Cox 2004-04-16 08:50:14 EDT

Whenever you create a file on an ext3fs filesystem, some amount of
other in-memory data, _not_ the file's contents and _not_ something
which is present in the same filesystem or which previously was in a
file at all, gets written to the device holding the filesystem.

Could be a security issue if you have stuff in memory like crypto keys
and don't expect them to get stuck on disk (well unless swapped)

Issue is a fairly minor severity
