CVE-2017-17046 xsa245 xen: ARM: Some memory not scrubbed at boot (XSA-245)
ISSUE DESCRIPTION
Data can remain readable in DRAM across soft and even hard reboots.
To ensure that sensitive data is not leaked from one domain to another
after a reboot, Xen must "scrub" all memory on boot (write it with
zeroes).
Unfortunately, it was discovered that when memory was in disjoint blocks,
or when the first block didn't begin at physical address 0, arithmetic
errors meant that some memory was not scrubbed.
IMPACT
Sensitive information from one domain before a reboot might be visible
to another domain after a reboot.
VULNERABLE SYSTEMS
Only ARM systems are vulnerable.
All versions of Xen since 4.5 are vulnerable.
Only hardware with disjoint blocks, or physical addresses not starting at 0
are
