&gt; A vulnerability I discovered a bit of a year ago allowed local privilege escalation for any user with access to write to an XFS filesystem.<p>So, mount any existing xfs file systems read-only, and move rw systems to ext3? I&#x27;m not saying it would <i>make sense</i> - but sounds like a prime example of something for which there was a work around...<p>(I&#x27;ll concede that for those that need(ed) xfs, there&#x27;d probably not be many alternatives at the time. Possibly JFS?)
