Subject: [PATCH] Fix crash in remoteDispatchDomainMemoryStats (CVE-2013-4296)
The 'stats' variable was not initialized to NULL, so if some
early validation of the RPC call fails, it is possible to jump
to the 'cleanup' label and VIR_FREE an uninitialized pointer.
This is a security flaw, since the API can be called from a
readonly connection which can trigger the validation checks.
This was introduced in release v0.9.1 onwards by
commit 158ba8730e44b7dd07a21ab90499996c5dec080a
