CVE-2017-7228 xsa212 xen: x86: broken check in memory_exchange() permits PV guest breakout (XSA-212)
ISSUE DESCRIPTION
The XSA-29 fix introduced an insufficient check on XENMEM_exchange
input, allowing the caller to drive hypervisor memory accesses outside
of the guest provided input/output arrays.
IMPACT
A malicious or buggy 64-bit PV guest may be able to access all of
system memory, allowing for all of privilege escalation, host crashes,
and information leaks.
VULNERABLE SYSTEMS
All Xen versions are vulnerable.
Only x86 systems are affected. ARM systems are not vulnerable.
The vulnerability is only exposed to 64-bit PV guests. HVM guests and
32-bit PV guests can't exploit the vulnerability.
MITIGATION
Running only HVM or 32-bit PV guests will avoid the vulnerability.
