Subject: [Qemu-devel] [RFC] sanitize memory on system reset
Date: Thu, 13 Jun 2013 08:09:09 +0200 [thread overview]
Message-ID: <51B96205.4010601@kamp.de> (raw)
Hi,
I was thinking if it would be a good idea to zeroize all memory resources on system reset and
madvise dontneed them afterwards. This would avoid system reset attacks in case the attacker
has only access to the console of a vServer but not on the physical host and it would shrink
RSS size of the vServer siginificantly.
BR,
Peter
